Mast mounted preamp project.
Two preamps, one for Vlf-Hf the other for 40-1200mhz
Mount in waterproof enclosures, seal ends, add static/lightning protection (replaced 90v gas discharge tubes with 60v tubes) add silicone moisture absorbers, fat more than needed, apply sealent to top and bottom of box lids, flood boxed with dry inert argon gas, seal up all over and mount. Both are bias tee powered, let's see how this works. Hopefully sealing the hell out of it, adding silicone and filling it with argon will defeat water condensing inside.
