I have toyed with this idea. But for mobile static I find it might be a bit of a faff/tricky. I could make 2 x 1/4 wave bits of wire attached to U-Bolts on the IMAX bracket and then if need be and add parachute cord to the radial ends as you did to get them down and attached to some fence or tree stump or bush etc.


The only thing is in the ARRL handbook I read that radials need to be very precisely measured and angled to spec otherwise unpredictable effects can start occurring to radiation pattern and TOA's.


(as we know we can make a normally omni directional antenna slightly directional to the tune of 1-2dB I think...by adding just one radial in the direction where you want the pattern to be skewed.)


Could it be that your friends internet monitoring station was just in a favourable location and gain was reduced in some other directions, TOA changed a bit ?
