All things being equal... IF you are using LMR-400 as the main feedline, there is NO REASON to use a different diameter at the rotator...
I was simply responding to what the OP said were the conditions... NOT the "ideal"... Bottom line... IF you engineer and install things properly, the fewer breaks in the feedline, the better... Fail to see why an antenna failure or swap would require soldering "up the tower"... unless for some reason you change feedline to antenna connector type.... not likely... or you compromised a connector termination or failed to weather protect properly.... In either case, your odds of doing one of those things increase with every additional connector you add to the line. BTW, using the -DB suffix (if available) for any Times cable will radically reduce the chances of moisture ingress on the feedline... ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 10/10/2016 6:49 PM, Josh Fiden wrote: > With an unbroken feedline, a failure or antenna swap can require > soldering connectors up the tower.
