[TowerTalk] Barker & Williamson Model AC - 1.8 - 30

[David Robbins]

easier to put a small transmitter board with short antenna on the drone and just match the gps track with received signals sampled on the ground.  
the biggest problem is deciding how far out from the antenna makes a valid far field pattern in real conditions... it may not be too bad for vhf, but 
for most hf stuff you would need a pretty big pattern to get valid results.

I've suggested before that it should be possible to attach something 
like a Softrock to a drone along with a small 3-axis sampling antenna. 
The output could either be stored in memory or fed real time back to the 
ground via some sort of link. The drone could be programmed via GPS (or 
simply positioned via a tether) to run concentric circles around any 
existing antenna in place at it's normal location to plot the radiation 
pattern. The result would take into account not only the antenna itself 
but also the impact of its surroundings (terrain, buildings, other 
antennas).

I don't think it would take too much engineering or cost to put 
something like this together, but I suspect that not many people would 
be willing to pay to cover the hassle of doing so. Maybe cell tower 
owners ...

I still think it's an interesting idea, though.
