I received the the XM Signal Repeater about 2 hours ago! It works as good or better than advertised.
I am on the 3rd floor of a 3-story hotel. The walls are built with steel 2x4s and the floors/ceiling panels are built with steel/iron rebar reinforced concrete..
I performed the following unscientific test.
I set up the signal transmitter in the hallway with it's antenna in the vertical position. I kept the signal repeater in the vertical position.
I used the 2-0-7 method to turn on the MyFi.
I measured out 75 feet. This was a straight line-of sight, with no visible barriers.
At 10 feet, BER % was 0.0
At 70 feet, BER% was 0.0
At 75 feet, BER% was 0.9
At 80 feet, BER% was 3.8
At 85 feet, BER% was 6.4
The advertised distance was exceeded.
I moved the transmistter into the room. I then measured 75 feet.
The signal had to move through 4 walls with steel 2x4s.
At 10 feet, BER % was 0.0
At 70 feet, BER% was 0.9
At 75 feet, BER% was 2.5
At 80 feet, BER% was 6.7
The advertised distance was met.
I then went to the first floor and outside. The maximum distance I could use, I calculated at 80 feet. There were 2 floors of iron/steel rebar and at least 4 walls with steel 2x4s, plus and enternal wall with rebar reinforced concrete.
At 65 feet, BER% was 2.2.
At 70 feet, BER% was 3.1
At 75 feet, BER% was 5.8
At 80 feet, BER%, was 8.7
I was not listening, just observing the BER%. It appears as though the realistic max distance under these conditions is 70 feet. Though it was not the advertised distance (75 feet), it was not a significant difference, giving the conditions.
I also maintained a BER% of 0.0 while inside the elevator traveling between floors. The distance from the transmitter to the elevator is 50 feet. The elevator is in a steel cage.
My personal experience is that is this accessory works great and as advertised. I strongly recommend the XM Signal Repeater.
Your experience may vary.
Happy Xm'ing,
