I like antenna manufactures , they will say anything to sell there great antenna.
Being a ham, I remember a bunch of years ago when in the radio magazines they would show a cool picture of a new antenna, give you the specs, and tell you this is the one.
The specs would be in dB . Today we get the same, but its in dBi. so whats the difference ? ( I am asking, I know the answer, but I am still asking you )
-10 dBI @ 30 Mhz is shit. Hell that's a not even a wet rock being loaded, its just a rock load.
The frequency span is big. That tells me that the antennas "Q". (look it up) is low. In trying to keep the antenna close to a low SWR, or resonant, designers will add resister(s) loads to the antenna, so the radio sees the antenna as a match to what even frequency it transmits on. Another way is to use traps.
Working in this RF field of Electronic Engineering, for a few days now. When I given some great new antenna, to solve all of my radio issues, I always look at the devils details.
I have not worn this system, I am just looking at the specs, but like another commo man once told me;
Its not an true antenna, but my hummers bumper got 5X5 ...
If it works then use it, I love field testing.
Being that the antenna is omni -directional I wonder what the E and H fields look like?
I also wonder if it works like a large capacitor, and the human body is the insulator in the middle?
