HyperGain 900 MHz Grid Antenna Test

Ok Fellows, I have been running a little test the last few days with a HyperGain 900 MHz 15 dBi Die-cast Grid Antenna. Let me explain the conditions in which the test was run.

Tropical Storm Fay has been sitting right over the top of my house for two days. We have had 74-mph wind gust with sustained winds of between 45-mph to 25-mph. The Cell tower is 9.89 miles away. We have had 21 inches of rain in the last two days.

I tuned the sucker in on the tower Thursday afternoon. Without an outside antenna hooked to my pc5750 card I get nothing. With an omnidirectional antenna with ground plane and without the amp inline the best RSSI I can get is –87 to –93 most of the time it runs –89. With the amp inline I get around –78 to –81.

I installed the HyperGain 900 MHz Grid Antenna with 50 feet of LMR400 and peaked the dish with no amp inline and the RSSI was between –78 and –80.

For the last two days during the storm it has maintained a –79 to –83. I think I lost signal maybe three or four times today, but usually it only lasted maybe ten to fifteen seconds and it would pop right back. I figure it was the 74-mph wind gust whipping things around that made the signal drop.

You don’t have to have a line of sight for this Antenna, and I must say I am sold on it from the little experience I have had with it. It’s the best Antenna for 900 MHz I have used yet. It’s light and easy to put together but you would need to use it in a base station setup because it is 23.5 in deep x 39.3 in wide and is for 870 - 960 MHz but works well with the Alltel service I have.

Hope this helps, it’s easy to get confused when you first get into this stuff, as I found out!
