Cell Phone Booster for RV Truck, 5G 4G LTE for All U.S. Carriers Verizon AT&T T-Mobile | Omnidirectional Antenna, Band 12/17/13/5/2/25/4/66, RV Cell Phone Signal Booster FCC Approved

I tried both power plugs it comes with and I couldn’t get it to work. I also try to contact the seller to see what we could do and heard nothing back from them

This Cell Phone Booster for RV Truck, 5G 4G LTE for All U.S. Carriers seems to work well, at least in my one tested location.I placed the antenna on the roof above the sliding door of a large van and the inside antenna was in the rear. Upon turning it on, the lights for bands 4, 2 and 5 became green quickly. The lights for bands 12 and 13 sometimes became green and sometimes flashed orange for a long time and then remained orange. This is in a city location with strong signals. In the testing below, those bands were not used, so it did not matter.The tests were done on the Verizon network with band 66 for LTE and 5G. Results of two locations, close to the inside antenna and far from the inside antenna gave the following results:Close to inside antenna:No BoosterSignal B66 -95 Signal 5G -102SS-SINR B66 16 SS-SINR 5G 13BoosterSignal B66 -79 Signal 5G -98SS-SINR B66 20 SS-SINR 5G 19Far from inside antenna:No BoosterSignal B66 -95 Signal 5G -102SS-SINR B66 16 SS-SINR 5G 13BoosterSignal B66 -88 Signal 5G -95SS-SINR B66 16 SS-SINR 5G 23In both cases signals were stronger and more importantly, signal to noise ratio improved.Speed testing did not show much difference as it was in a good signal area. Downloads were always in the 400 Mbps range. Uploads seemed to improved slightly from 25 to 35 in some cases, hardly a change in others. More testing would need to be done in low signal areas and with other carrier bands.The antenna is pretty large, and I am guessing it really does not need to be that large. It is not heavy and feels pretty empty. They provide mounting hardware for both vertical and horizontal pipes and bars. The mounting hardware is pretty beefy. They provided flat and lock washers and what looks like stainless hardware. That combination is not that great, with a tendency to gall and a tendency for the lock washers to come loose. Some Loctite 243 was used to lock everything down and prevent galling.They provide an antenna wire and an extension. The antennas are 75 ohms, with a SMA on the antenna and F connectors otherwise.The booster unit itself is easy to connect the wires to and easy to read the front panel. An explanation of what you see is included in the instructions.The inside antenna is pretty small with a long cable, and there are Velcrow patches to help mount it.From my testing, best results happen with the device close to the inside antenna, maybe a few feet. This appears to work quite well. We will see what happens with further testing in weak signal areas.
