[Antennas] MORE " G5RV " ANTENNA QUESTIONS !!!!

[j.hilton1]

HI again,
              And first off all many thanks to all who helped me with my =
last questions I asked on here regarding the full size 80 - 40 mtr G5RV =
antenna I had installed recently, a few more questions regarding the =
above, if anyone can be so kind as to help me out again ?? have the G5RV =
installed with the centre point at around the 25 feet level just below =
the rotator holding the 6 mtr beam with both 51 feet legs coming sloping =
down there full length to the ends which are supported at 10 feet each =
side. the problem that I have is that the feeder which is 30 feet 6 =
inches off 450 ohm ladder line is more than enough to feed from the =
centre off the 5RV to the actual radio, according to the instructions =
supplied with the antenna any length off 50 ohm coax cable can be =
attatched to this ladder line, so whats best to do ?? bring the ladder =
line into the shack and attatch a small length off coax cable to it, say =
2 feet in length ?? or loose some length off the ladder line on the =
outside by having it going further down the tower first ?? to  then =
attach the coax cable say 10 - 15 feet in length ?? from the radio going =
way out to the end off the ladder line ?? also many thanks to the =
amateur who    advised using a length off platic tubing to insulate the =
ladder line from the actual tower, great idea !! using the inbuilt tuner =
with the yaesu ft920, am I likely to be able to get a sattisfactory tune =
on all bands 80 -40 mtrs using the above arrangement ??

As always thanks to everyone who helps me out with any tips / advice it =
is always very much appreciatted.
