I agree interesting.
So goretex is basically invisible?
HMMM..Syed is saying a Lantern will still decode at a SNR of 2. I think.
I am able to get about 7-8 in tropics lying down flat the bare DIY antenna and open sky.
Under a blue plastic tarpaulin i get like 6-7 SNR
If I put a fiberglass radome dome i intend to use as a radome over the DIY Lantern antenna and still under the plastic tarpaulin i can get about 5.5 snr.
So it appears anecdotally a Fiberglass Radome 1mm thick has a SNR attenuation of 1.5 to 2.00.
Bringing my normal signal to from eight SNR to six.
Six is probably plenty in the tropics except on the most severe rain fade events.
On question is shape of radome. One of the forums talked about the radome material refracting the signal. Is this worth worrying about at 1.5ghz.
