 Does as claimed
By David M. Calaman
A little pricey, but works as described. It didn’t work very well with the omnidirectional outside antenna. Could not get enough seperation between inside and outside unit. Replaced outside antenna with directional yagi, and things worked like a charm. Only problem is, it adds another $80.00 to the price tag. Where I used this, I had less than 1 bar on the phone. Usually calls would drop in the first minute or so. With this unit, calls are solid with about 2 bars on the phone, as long as you are in the room where the inside antenna is installed. I was also able to maintain an internet connection with the Verizon broadband/National Access service. I used the unit in a house, and not a RV or boat, so I can’t offer any thoughts on how it would work for RV or Marine.

 Does not work as advertised.
By E. Martinez
While this may work, to improve reception in a building which has marginal signal inside, but adequate signal outside, this definitely DOES NOT increase range by 30 miles on RV’s and boats. I specifically purchased this for my boat (they advertise a lot in boating publications and target the market). I installed the system exactly as instructed. I had the outside antenna on a mast above the boat (a Nordhavn 40 trawler). The antenna was 30 ft above the water. The inside antenna was mounted on the lower deck in a stateroom, with the antenna facing down and away from the outside antenna. There was at least 3 Fiberglass and wood bulkheads (Walls for you non nautical types) separating the antennas. I took the boat off the SW cost of FLorida (Marco Island) and started heading south. I usually lose signal about 9 miles south of Marco (Verizon). When I was down to 1 bar on my phone I powered up the amp. No difference, I had to literally put the phone directly underneath the inside antenna to get a few more bars, and then I only had signal for another 2 miles. I had the same experience with my Sprint MIFI card.
So lets see, over $500 + expense and trouble to install this thing under the best of circumstances (over water, line of sight to cell towers), only to get 2 additional miles over my hand held phone. Save your money, it just doesn’t work.
