Martin,
Before going to a G5RV, I would try feeding your 80 m dipole with 450
ladder line to a (good) 1:1 current balun and use a short run of coax to
the K1. I use this setup to feed 102' and 44' wires. My Ks tune them
on any of the bands they cover (you need a bit of additional L/C help on
160) and they work great.at QRP levels.

Hi Guys, my main rig is a K1 feeding a multi dipole for 80/40/20 with no
ATU. I am thinking of taking down the dipoles and trying a full size G5RV.
Questions:
Will the KAT1 ATU tune up on all bands from 80-15m
I will be using about 80 feet of 50ohm coax to get from the matching
section to the rig, am I going to get big losses in the coax due to the
high SWR on most bands? The beauty of the G5RV is that it can be fed
with coax but with only 5W I don't want to waste all the power in the
feeder.
I intend to build the G5RV myself (like all of my antennas), how
accurate does the length of the matching section have to be? does it
need tuning in some way. Can I use any insulated wire for the open wire
section?
The multi dipoles have been great performers but it's a lot of wire up
there and very heavy, I thought that with the G5RV being one single top
wire it will be lighter and I may be able to get it higher.
Any thoughts would be appreciated.
