nayrExcellent Portable RepeaterReviewed on Feb 18,2025Fixed installed on my Toyhauler Camper w/a Multi-Polarized 1/4 wave NMO (08-ANT-0864), and a 6 Pack of RT22 Handhelds all on licensed GMRS for use somewhat near camp. Ive built my own GMRS repeater before and this has better audio and is much more portable and power efficient.The handheld coverage is far more solid than simplex, being inside a building like the showers/bathroom does not cause issues like before, the handhelds can hear the repeater from much further away than they can be heard, like 8m+ Rx and 2-3m Tx. The range is perfect for base camp, we switch to simplex if we have a bunch of handhelds too far out from base, could likely gain range for HT's with a higher gain base antenna but I don't need it and this multi polarized wideband antenna is getting me great audio without LoS and better range in Canyons.Mobile Rigs can now venture off at great distances and keep coms, tow vehicle has 25W with 5/8 wave radio and I've got over 15 miles out, and from behind obstacles I didn't think would work like earthen dams. Anyone in base camp can communicate with the far-off mobile rigs with a simple handheld, audio is clear. This is great and just what I wanted, I can install nice radios with nice antennas in toys such as OHV's and Boats and still communicate with base camp over large distances.FrankWell designed and very functionalReviewed on Feb 01,2025Very impressed with the build and abilities of this repeater. Well designed and very functional. Once ordered you will receive a message from the company about any special programming you may desire. For me I simply wanted the typical GMRS repeater frequencies programmed into the unit. They said it may be 30 days before delivery but - for me it came withing about 10 days. Easy set up and worked great. Now just trying to locate a good high location for the repeater to be placed in an emergency. I would definitely recommend this repeater as a very good purchase and value.PaulGood repeater so farReviewed on Jan 22,2025I am starting off with a 4 star, I will edit in the future should it change. Repeater up and running for about a day now. Good coverage and noce clear audio.Shipping from Hong Kong was super quick less than 2 weeks. Retivis customer service resp were great making contact a few times.Only complaints so far, dodnt come programmed with the correct gmrs freq. However programming cable and a software download made short work of that. Antenna quality height and over all placement is more important that wattage anyway.So far I am happy with my purchase. Thank you retivis.Isaac U.Very unique product allowing you to easily jump into GMRS with duplex repeaters.Reviewed on Jan 10,2025Out of the box this thing was ready to go. I was easily able to get my handhelds programmed and working with this repeater. We use it as a city wide repeater for my friends and family. It covers 5 square miles pretty effectively on a 40' tower with the Retevis base station antenna. I also had it deployed at a summer camp in a heavily forested area on a 20' pole and it worked very well for over a month. The unit only had to be rebooted once when the squelch got stuck open.All and all, this is a great starter for folks playing around with GMRS radio.JanellGreat emergency communication RepeaterReviewed on Nov 10,2024This repeater works out of the box. Power and hopefully a good antenna and location. Altitude of your antenna is essential. You are only getting about 5 watts out of the transmitter and duplexer. But no complaints. You get this unit high enough and you can attain really decent coverage. It would have been nice if they put a station identifier into the unit but it's really for quick and ready communications. Worth a buy. I hear a new version coming out soon...Laura SchnebergerReally makes life easier to have dependable communication.Reviewed on Oct 18,2024Works great may have to get one more to cover all the nooks and crannies in our twenty square mile mountain ranch. Highly recommended.AaronNice repeaterReviewed on Oct 12,2024I recently got back into radio, and figured I would set up a GMRS repeater. I bought the Retevis RT97s and have been pretty happy with it. The setup is easy. Unfortunately it doesn't appear to be compatible with CHIRP, but it does have a Windows-based app for making programming changes.KennyRT97s RepeaterReviewed on Sep 11,2024I love it. I have it hooked up temporarily until I can get my antenna on my roof. Great product. Small compact and easy to transfer over to my vehicle.WayneGreat for the farmReviewed on Sep 10,2024This increased our coverage from 3 miles to six miles/Coverage on a 35' push up pole on a silo.Really helped our portable radios along with increased our coverage in our vehicles from around 3 miles to 9 miles.Really great product and worth the buy.kris pertlike RadioReviewed on Sep 10,2024Like Radio All Revis
