ORM T-MARC (Tactical Modular Antenna Relocation Cable)

Relocate the annoying radio antenna

Made with robust materials, the ORM T-MARC (tactical modular antenna relocation cable) will allow law enforcement and military service members to operate in the field without worrying about their communications equipment getting in their way. T-MARC cables feature either a 90° right angle connector or a straight at the radio end and a straight connector at the antenna end This allows the operator to mount the radio on the front, side or back of their gear while helping eliminate physical interference and while placing the antenna’s line of sight higher on the operator’s body.

Additionally, each T-MARC system features nylon braided sleeving over the cable. This helps protect the cabling while offering a variety of colors to accompany camouflage. Sleeving colors available are:

  • O.D. Green
  • Black
  • Charcoal Grey
  • Coyote Brown
  • White
  • Woodland Camo
  • Desert Camo
  • Multicam
Additional sleeve colors are available upon request and the additional color options are available for viewing on the T-MARC FAQs (below).

The ORM T-MARC cable is not limited to Law Enforcement or Military use. The T-MARC cable can also be used by those within the security field, explorers and anyone that runs communication gear in airsoft or Milsim (military simulation) scenarios. The ORM T-MARC cable is beneficial to anyone using two way communications gear and external body armor/plate carriers.

Motorola HT750/HT1250 radios and ICOM F Series radios will require you to purchase a different antenna in order to interface with our cables (either from us or elsewhere). SMA and BNC antennas are some of the most common antennas available for portable radios at affordable prices. If you are ordering a T-MARC for a Motorola HT750/HT1250 or an ICOM F Series radio, please specify the style of antenna that you will be using instead of the factory antenna (either a BNC. TNC or SMA antenna).

You also have the option of having a 5/8 omni directional 3-6 dbd antenna pre-installed to your cable. This is definitely not a requirement, but if you are looking to replace or upgrade your factory antenna with something that is more robust, just select an antenna from the drop down menu.

Each T-MARC cable is constructed in the USA with quality components and is tested for quality control after construction and before shipping. We do not and will not use sub-par or cheap Chinese components with our products!





ORM T-MARC Cable

T-MARC FAQs

What is the T-MARC?

The ORM T-MARC stands for "Tactical Modular Antenna Relocation Cable". It is a cable that is specifically built to move a two-way radio antenna from on top of the radio to another location on the wearer's body.

Why would I need a T-MARC?

Often, when operators are using radio communications gear with VHF or Multi-Band radios, the antenna can measure between 6" and 16" tall. Depending on where the operator wishes to wear/place the two-way radio (usually when mounted on an exterior body armor carrier or plate carrier), the antenna can cause potential interference with visual line of sight, weapon manipulation, weapon placement, other gear, and dexterity; especially when transitioning from a standing position to a seated on (like when trying to sit in a vehicle). In order to alleviate these problems and offer a higher line of sight for radio communications, the T-MARC is routed through the exterior body armor carrier or plate carrier, one end of the cable is connected to the wearer's radio and the antenna is connected to the other end (typically at a higher point on the body (i.e. shoulder area)). This provides a greater degree of freedom for the operator while helping eliminate interference and obstructions.

How do I know what length T-MARC to buy?

The easiest way to measure for your T-MARC is to mount your radio in the position in which you wish to have it. Then take a piece of string or 550 cord (parachute cord) and run it from your radio, through the exterior body armor or plate carrier webbing and up to one of your carrier's shoulders. Once the string is routed, mark the string and remove it from the carrier. Now you can measure the total length of string up to the mark that you made. That distance, in inches, is what you will place in the "cable length" box during ordering.

You can also guesstimate on how much cable you will need. However, since the idea is to route the cable with as little exposed to prevent snagging, this method is not suggested.

What options are available for the T-MARC?

Options for different radio systems and colors are available to suit a wide variety of applications. Most of which are available at our store. If you do not see an option available, do not fret; just contact and we can make a custom cable for you.

Who is the T-MARC designed to be used by?

The T-MARC is primarily designed with law enforcement and military personnel in mind. With that said, the T-MARC can also be used by security and security contractor personnel, survivalists, as well as Airsoft, Paintball, and MilSim personnel. Basically, anyone that is using a radio communication system and is wearing gear that the antenna can attach to is able to use the T-MARC.

Is the T-MARC made with quality materials?

YES. We designed the T-MARC with emergency services personnel in mind and communications within that realm is crucial; in fact, their life depends on it. Because we want the T-MARC to operate flawlessly in adverse conditions and in high-stress environments, we only source high quality, mil-spec materials from our vendors. We will never use cheap, counterfeit or low standard materials in our T-MARC cables.

Is the T-MARC made in the USA?

Yes. While some of our vendor components come from Germany or Japan, the T-MARC is 100% Made in the USA by skilled Americans that have a background in RF Communications.

Why is the T-MARC so cheap when compared to some of your competitors?

This is because of a couple of reasons.

First, we understand that we are operating in a niche market and our potential clientele is rather narrow compared to if we were selling a standard product to the masses. We also understand that, within this niche market, law enforcement or military personnel are often buying this type of gear out of their own pocket verses receiving it from their department or company. We would much rather be more available to our clientele and make a smaller profit than attempt to alienate our customer base and strive for larger profits.

Secondly, we employ a lean manufacturing process that offers us the ability to operate without a large overhead. While this means that it may take 3-5 days before your T-MARC ships, it also means that we can keep costs down since we are not buying components/equipment that is not required.

Finally, we are not spending a lot of money on advertising, marketing, and trade shows. All of these tactics allow us to produce a robust and quality product without having to charge an arm and a leg.

Can I order a T-MARC with an antenna already installed?

Yes, you can. We now have an option on our store to order a T-MARC with an applicable antenna already installed. At this time, we only have a select amount of antenna options available for the VHF and UHF bands but we are working to also bring in more options for Multi-Band antennae.

Additionally, the antennae that we use also adhere to our quality and performance standards. You may think that you are better off using a cheap radio antenna from eBay but the fact is, a lot of those cheap antennae are clones/counterfeit from China and they will not perform well over time. The antennae that we offer may seem a little pricey, but you are paying for the quality.

What radios will the T-MARC work with?

For the most part, if the radio has a removable antenna, a T-MARC will be able to be installed. Below is a partial list of applicable portable radios, if you have any questions about if a T-MARC will work with a particular radio that is not in this list, feel free to email us at sales@ormohio.com.

  • Motorola MT Series
  • Motorola Saber Series
  • Motorola XTS Series
  • Motorola APX Series
  • Harris AN/PRC 152
  • Harris XL Series
  • Thales AN/PRC 148
  • Kenwood TK Series
  • Kenwood NX Series
  • ICOM F4000 Series
  • ICOM F1000 Series
  • ICOM F3000 Series
  • ICOM F7000 Series
  • Vertex VX Series
  • Most BaoFeng portable radios with removable antennae
  • Most TYT portable radios with removable antennae
  • Retevis portable radios with removable antennae
  • TRI Tactical radio clones (TRI PRC 152, TRI PRC 148, etc)

We can also make custom cables for SINCGARS radios such as the RT-1439, RT-1523, RT-1523, AN/PRC-117, AN/PRC-119, and AN/PRC-154. Just email us with information concerning your particular application.

Why do you ask for a Radio Model on the order form?

This is primarily set up as a fail-safe measure. With us knowing what radio you wish to use the T-MARC for, we can potentially catch an accidental connector option prior to building and shipping.

For example, if you are wanting to get a T-MARC cable for a Motorola XTS5000, which uses an SMA-Female connector, and your selected option for the radio side connector is a TNC male, we can then email you to confirm your connector choice. Some people are not sure which connector to order (by the way, you can always as us before ordering) and we don't want you to open your T-MARC and then be disappointed because you can't use it due to the wrong connector being ordered/installed.

How long of a T-MARC cable can I order?

Typical T-MARC cables (that are physically worn) are between 12" and 48" in length. However, we technically have the ability to make custom cables up to 50 feet in length (orders for cables over 48" (4 feet) in length are custom and we must receive an email request since that length does change cable pricing).

Keep in mind that we will contact you if you do order a T-MARC that is longer than 10 feet in length. We do this because we want to make sure that your order wasn't the result of a typo and we want to make sure that the requested length of cable is applicable to your end use. After all, if you attempt to use a 5-watt radio with 50 feet of cable, the total signal loss involved basically cuts the radio output to 1.5 watts instead of the original 5w; you will not get the performance that you are wanting.

Can I order a sleeving (braiding) color that is not on the list?

Yes. We have approximately 18 different color options that we can get from our vendor but we only listed and stock the 7 most common colors on our store. If you want a particular color from the following list (Airsofters and Paintballers), just email us and we can do a custom order for you.

  • ACU Digital
  • Acid Purple
  • Dayglow Yellow/Neon Green
  • Imperial Red
  • Multi Camo
  • Neon Green
  • Neon Orange
  • Neon Pink
  • Neon Turquoise
  • Neon Yellow
  • Royal Blue

Is there a warranty on the T-MARC?

Due to the variable environments that the T-MARC can be deployed in, we offer a limited warranty on the T-MARC cable.

T-MARC cables are covered by a limited 12-month warranty. Warranty coverage is limited to defects in manufacturing or materials. Items physically damaged or when there is evidence of improper use are not covered under the product warranty. ORM does provide reasonably and discounted repair services for non-warranty repairs and do, on occasion and with prior approval, repair product manufactured by other companies as a courtesy to our customers.

Do you offer bulk T-MARC discounts?

Yes, we have a basic discount for 3 or more T-MARC cables available on our ORMOhio Store. If you are a government agency, police department or military unit, contact us before submitting a bulk order and we may be able to grant you an additional discount for your order.

Are the connectors available in black?

There are a couple 'black' connectors that we have found and we are currently testing them. So, while we may offer black connectors in the future, they are currently not available.
