[Antennas] " G5RV " TYPE ANTENNA / "CUSHCRAFT MA5V" ANTENNA QUESTIONS

2002年6月30日 21:30:38 +0100

Hello all, Looking for some kind help with the following questions regarding
my newly purchased "g5rv" - type antenna, it is the full size 80-10 mtr 102
feet version with the 30 feet 6 inches off ladder line feeder, the questions
are regarding the coax cable to join to the ladder line, is there a minimum
length off cable I would have to use to gain a good match ?? my plan is to
mount the centre section off the antenna at a height off about 25 feet at
the top off my tower with both sides coming down to either side off my
garden, likely results with this style off layout , as far as dx / local
working ?? any problems with running the ladder line down about half the
length off the tower and then joining the coax cable there ??
Lastly, unfortunately I have telegraph pole very close to the very end off
my garden with the actual phone line crossing above the garden at a height
off around 20 feet, am I likely to experience any problems with
intereferance, etc ??
Regarding the " cushcraft ma5v " 20 -10 mtr vertical, anyone on here actualy
use one off these antennas on the ssb portion off the bands give me any tips
on tunning , extra weatherproofing required ?? etc, any tips before
attempting the new antenna systmn project !!
As always many thanks to all who answer my questions it is very much
appreciatted.
REGARDS,
