@chuckr We have one radio on the roof in a non-weatherized plastic enclosure. Our early receivers were placed in ziplock bags. We then graduated up to tupperware containers. The plastic should not degrade your signal, as long as you don’t have anything touching the antenna.

Hi Andrey,
which component in “the package” you got from Syed fixed your problem? Or did you replace the whole system?
I really like to understand what made the difference
thanx

@chuckr You definitely can leave the antenna outside in a plastic box. Your coax losses at 1.5GHz are pretty horrid. It’s about 32dB loss per 100ft. for RG-316. So what you really want to do is to run power to a plastic box containing the antenna, the LNA/SAW filter, the SDR and the receiving computer (or any combination that does all of that). Seal the hole you make for the power supply well.
One of those snap-top lunch containers would probably work great.
thanx for the info. LNAs seem to be quite fragile!
There is no shortage of articles on ESD protection for LNAs. Here’s an application note:
