Porthole heatspreader for 5.7GHz masthead enclosure
The new 5.7GHz system is ready to mount on the dish, on top of the SCAM12 pump-up mast with the tilting 95cm offset dish and 10GHz system. I’m using a Schneider IP66 rated case made from mild steel with a powder-coated finish. I’ll be adding cable glands and a Gore-Tex breather plug, and flushing the case with dry Argon, and adding a silica gel pack before it is locked and fitted on the mast. The existing 10GHz kit is in an identical case, but I’ll be moving it to the new dish, which has a -7 to +57 degree elevation drive and well as 450 degree azimuth rotation. Initially, I won’t fit the 12W PA, as I haven’t finished it yet, but everything else is sorted and will go in the box tomorrow.
