Rg400 is decent coax . I've used as much as18 feet on my quad mag mount. For jumpers should be fine .check the wattage rating on the coax . And never use 1 foot jumpers way too short ..I recommend 6 foot or 9 foot.i 've seen high defect going back to the radio with shorter than 6 foot jumpers
After having my older friends had one of course I wanted one. I got my chance in1993. Stated with a cobra 19 ultra and cheap antennspa.my first base station came in 1996 I had a 40ch. C ourrier. And a99.thru.the years many different setups
Having owned the Imax and switching to a sirio 2016 . I'll take the aluminum any day over the fiberglass ..mainly cause the receive seems quiter .I never owned the maco but I would think results would be similar.also those fiberglass do have great swrs ,but so do dummyloads
If ya already have a swr of 1.1 trying to improve that is a waste.in fact anything below a 1.5 is acceptable.I always try to keep my reactance or X as low as possible ,even if it slightly raises swr.next I try to get my impedance or R as close to 50 ohms as possible. All this before I worry...
The colossal 10k is built way better than the sirio . And most likelybetter then spt500 and maco..it should perform just as good as the sirio ...not sure about better.
