[TowerTalk] Precip static on an LP

I would expect two factors at play. The main factor is probably the 
large surface area of metal up there to collect the static. The other is 
the broad bandwidth. A better solution in terms of precipitation static, 
performance, size, weight, etc.,  would be a SteppIR. I suspect that 
even a 2 element SteppIR would be similar in performance, and a 3 
element much better. A 4 el would replace the whole setup with better 
performance and no interaction (and a thinner wallet, of course).
