The radial kit alone won't fix cmc on the imax or a99,
you should be ok with the spt500, if you have any issues, isolate it from mast & choke the coax.
I suppose I should just keep the GM. I've had it since they hit the market. I had an IMAX and Antron before it. I dealt with neighbor complaints with both of those. The GM is problem free in that regards.
I am curious why you used 8x coax instead of 213 or similar coax on a 100 foot run?The coax is in good condition. I used quality 8x. It's been cobbled where I ran it in different directions over the years, but want to refresh it. I have some nice LMR-240UF I picked up couple years ago. Just got lazy and put it off. Recently, both my wires came down due to rotting cord or darned squirrel. Not sure, but it looked chewed. I took that opportunity to replace with new. Just have the GM left to re-coax.
I scanned my GM with binoculars today. It looks good from the eye. I might just order a new GM. It's very difficult to lower my mast, especially at my age. Just want to do it once. I always use my analyzer. I'll have a 100' run to the GM.
Got it, thanks.I guess I should clarify. The old 8x is 65'. The LMR-240 will be a 100' run to allow enough length, if i decide to switch to a different location within the house. I
if i had a gain-master up & it was holding up to wind & the power i wanted to use,
i would not think about swapping it for another 5/8wave, you aint missing anything.
