To get your GMRS Radio system on the air, you'll need some equipment. Depending on your needs and budget, your GMRS equipment may include one or more hand-held (walkie talkie), mobile radios or "base stations," antennas, power supplies and adapters. Fortunately, GMRS radio equipment is inexpensive and easy to obtain.
Most of the radios we're recommending are used, and have come out of commercial service where they have been used by police, fire and other first-responders. These are rugged, durable radios that are built to last, and are highly configurable. They are also simple to operate, with fewer buttons and unnecessary functions.
Here are some of the radios, antennas, power supplies and accessories we've tested and recommend:
Portable HT (Handi Talkie), Hand-held Radios
Portable HT radios are self-contained, battery-operated radios that you can easily carry with you. HT radios can also be used as a mobile or base-station radio, using an external antenna and a PL259 to SMA coax-to-radio antenna adaptor. They're not as powerful as Mobile or Base-station radios, and will usually put out between 5 to 8 watts of RF power. You will need a battery charger with these radios, and a spare battery is a good idea. There may be other, useful accessories, such as a holster, belt clip, or an external coiled-cord microphone/speaker.
For maximum versatility, you will want to select portable radios that can be programmed to use GMRS "Repeaters" to increase your range. However, there are also perfectly good portable radios that do not use repeaters that can be used during camping trips or in vehicle caravans to stay in touch with your friends or family by using "simplex" (direct, radio-to-radio) communications.
Kenwood TK-380 (type 1: 450 ~ 490 MHz) - These are very solid, well-made hand-held radios. There are many good, used TK-380s available online for under $100. Be sure to buy a new battery since used batteries may not hold a full charge. They also have a detachable antenna, and you can replace it with a Nagoya 701C for better range on the GMRS Channels. These radios often require re-programming to get them set up for GMRS Channels. They can also be programmed to accept special Pager Alert Tones.
NOTE: These radios come in three models: Type 1 (450 - 490 MHz), Type 2 (470 - 512 MHz), and Type 3 (400 - 430 MHz). Be sure you get the Type 1 model that covers the GMRS channels.
Mobile or Base Station Radios
Mobile radios typically have more power and greater range than portable, hand-held radios. They require external 12-volt DC power, usually supplied by your car's electrical system. They also require an external antenna, attached to your car either with a clamp or a magnetic mounting base.
Mobile radios can also be used as a base-station radio at your home or office. Base-station radios require an external 12-volt DC power supply and an outdoor antenna.
Motorola Radius GM300 - These are very good, used mobile radios, and can also be used as base station radios at home or office with an external power supply and outdoor antenna. They offer higher power, up to 45 watts, and have a greater transmission range. They do require some programming to get them onto the GMRS frequencies. They can also be programmed to accept Pager Alert Tones.
These radios come in many different versions so be careful to check the model numbers before buying. The model numbers carry a great deal of information, and it's easy to pick the wrong version of this radio. Look for model numbers that start with M44GMC29C3. This is a 40 watt, UHF radio, 45.1 MHz IF, wide spacing (20/25/30 kHz), 16 channels, expanded logic board, 438-470 MHz band. As always, ask us first if you need help in selecting or acquiring radios.
NOTE: These radios are often sold used without a microphone. Be sure you get a compatible microphone with the radio, such as the Motorola Radius HMN3596A Mic.
A good antenna can make all the difference in signal strength, both for transmitting and receiving. Antennas come in two, basic models; Omni-directional and directional:
Omnidirectional Antennas - These are the most common type of antenna used with many GMRS radios. Also known as "Vertical Antennas," Omni-directional antennas are usually composed of one, single antenna wire or element, and typically mounted vertically, straight up like a flag pole, with the radio or cable attached to the bottom. Your car's AM/FM radio antenna is a vertical antenna.
As the name implies, these antennas receive and transmit equally well in all directions in a complete, 360° radius around the length of the antenna, with very little signal coming off of the end. The little "whip" antenna on a Handi Talkie is a good example of an omnidirectional antenna. All portable radio antennas are omnidirectional. Almost all mobile antennas, and most base-station antennas, are omnidirectional.

Directional Antennas - These antennas are used with GMRS base station radios to improve reception in weak-signal (or "fringe") areas. Signals can be weakened by hills, trees, buildings or weather between you and distant stations. Sometimes known as "Yagi Antennas," directional antennas typically concentrate almost all of their signal in one direction, with very little signal coming off of the sides or back of the antenna. The conventional roof-top TV antenna on top of a house is a good example of a directional antenna.
Directional antennas offer higher signal "gain," or range, in one direction and are usually pointed directly at a GMRS repeater to improve reception and transmission. The gain can be as much as 6 to 9 Db of signal improvement over an omnidirectional antenna but only in one direction. Each 3 Db of gain is equal to doubling your signal power. For example, the power from a 20-watt radio fed into a 3 Db gain antenna is effectively doubled to 40 watts. The same 20 watts of power fed into a 6 Db gain antenna is effectively quadrupled to 80 watts, and the power of 20 watts fed into a 9 Db gain antenna is increased by eight times to 160 watts.
Like omnidirectional antennas, directional GMRS antennas are also typically mounted vertically, with the high-gain (or smaller) end of the antenna pointed at the desired distant station or Repeater.
