Hi
By reading the postings, it feels like a 20°x2=40degrees upto 30°x2=60 degrees cone would be OK
It should pick up the minimum over a reasonable surface below.
I see no value in NOT detecting the cliff in the given example 20ft on 150 feet, I hope it does detect the cliff. At 150ft/150ft it should not detect the cliff.
The angle of the cone also solves the problem of being not guimbaled and still providing correct reading with banking up to 20-30 degrees.
One of the days I'll check this with the TRA3500
Added : by re-reading the TRA3500 specs I found : "Antenna's response angle when mounted +- 6 degrees from horizontal = Dual : +- 20degrees for pitch, +- 30 degrees for roll.
So the designer adapted the cone for 30 degrees banking and 20degrees pitching.
At 150 ft it should detect the cliff from 50 ft at the front/rear, and from 70 feet sideways.
