4 foot tower mounted dish

 

 

 

Waveguide ( round )  is a 65 foot run of 3/4 inch copper pipe ( found at virtually any hardware store ) 3.2 db of total measured loss including right angle bends.

 

 

SMA launch at both ends of waveguide provide RF interface ( photo not too good )

It use a standard flange mount SMA connector positioned at a fixed offset away from the end of the pipe cap end. The center conductor protrudes into the copper pipe as a RF launch ( @ 0.25 inches ). Standard threaded screws are placed at one or two locations near the launch to provide a SWR matching. Rotating the end launches provide further matching when everything is connected together.
