Today I made some final adjustments and could achieve this with LMR-400 cable, 45.56’ of coax from RCS-4 control switch to remote coax relay box in the tower, and 60.74’ from relay box to Vector 4000 @ 16 feet above roof. SWR reading taken with a SWR/Watt meter at the station.
SWR———FREQUENCY
2.0—————27,985
1.5—————27,665
1.1—————27,245 ( Channel 25 )
1.5—————26,765
2.0—————26,295
Bandwidth = 1,690 KHz
This SWR is the lowest I could achieve. I’ll leave it right there.
By the way, I could get a Mini 1300 analyzer that could measure + and - X . Here are the reading taken today as well . By the way, I used one 12.5” RG-58 short jumper and a 7’3” LMR-400 jumper. Both practically gave me the same readings @ 6 feet above roof.
SWR——Frequency———R————-X
2.0————27,985———25.6—— + 3.3
1.5————27,530———34.1—— - 1.8
1.0————27,040———50.9—— - 0.4
1.5————26,665———62.8—— + 16.7
2.0————26,365———57.4—— + 36.1
Bandwidth = 1,620 KHz
