The rugged TERA TR-500 is a reliable 16 channel multi-use dual-band Commercial & Ham handheld two-way radio which is ideal for public safety, businesses, industry, S&R, CERT, ARES, RACES, preppers, or EmComm emergency communications.

The TR-500 provides reliable land-mobile, ham and emergency radio communications for law enforcement, PIs, public safety, Neighborhood Watch & CERT groups, businesses, Hams, and preppers to keep in touch when other methods of communication break down.

Designed in the U.S., these are sturdy, full power, commercial two-way radios with high performance and great (loud) audio output and an IP54 Dust & Water (splash) Resistant rating. With our signature ReadySafeGo™ service, we test each unit (including antenna), charge the battery pack, and custom program for you (see options above), so your new radio is guaranteed to be usable the second you open the box, and to NOT be DOA!

The TR-500 operating range is as good or better than any other affordable Commercial/Ham radio, even with its stock flexible antenna, which is better than most radios in this price range. As well, with our hi-gain whip antenna upgrade or an external mobile-mount or roof/tree-mount antenna (for base station use), you will see a significantly improved talk range, even when communicating with another stock handheld. The TR-500 is also repeater-capable (even split-band), greatly extending the potential operating range.
Commercial/Business/Ham Radio
Pre-programmed with 14 PLMRS (Private Land Mobile Radio Service) UHF and 2 MURS (Multi-Use Radio Service) Channels, allowing direct handheld to handheld communications. Ideal for security patrols, private investigators, business communications, schools, universities, construction crews and other organizations that have FCC licensed frequencies. Also great for Amateur Radio (Ham) communications, including ARES and RACES. Full 5 Watts of transmit power on VHF and 4 Watts on UHF for increased range. Note: We offer custom programming for this radio – see the Radio Programming Options above!
Voice Announce
Built-in voice announce feature for memory channel, battery level, channel lock/unlock and scan on/off status. Note: For FCC compliance, the hi/low power side button has been disabled (user-programmable with optional USB cable, or with our additional custom programming service – see the Radio Programming Options above).
Simple Operation
Easy to operate radio with its compact size and simple to use top mounted volume and channel knobs. Each radio includes a Li-ion rechargeable battery (which provides up to 30 hours of operation between charges with battery-saver mode), 2 hour desk charger, flexible antenna, belt clip & user manual.
Rugged Design & 2 Year Warranty!
Rugged handheld radio designed in the U.S.A., with loud receive audio. Backed with an industry leading 2 year limited warranty, and designed, supported and serviced in the USA (Southern California).

Note: PLMRS (Private Land Mobile Radio Service) operation is a coordinated band and does require an FCC license. Amateur Radio (Ham) operation also requires a license. This radio is not “type-accepted” for use on some bands such as GMRS, FRS and MURS.

IMPORTANT: Custom programming for this radio is meant for licensed use or emergency communications during emergency or “SHTF” (S#it Hits The Fan) situations. You are solely responsible for operating this device in compliance with FCC licensing and regulations, regardless of how it comes programmed. We are not responsible for any harm caused by the use or misuse of this device. Let us know if you have any questions before purchasing.


Channels:16 VHF or UHF channels, including handheld to handheld “simplex” channels or repeater “duplex” channels (even split-band offsets). Note: We can custom program the radio for business or emergency communications – see the Radio Programming Options above and Custom Radio Programming Chart below for all available settings!
Battery:Operate 30+ hours between charges with the supplied 1600 mAh lithium-ion battery in the power saver mode. Includes voice announce to indicate selected channel and to monitor battery life.
Applications:Ideal communications for businesses, security personnel, private investigators, schools, industry, preppers & (amateur radio) Hams to keep in touch.
