shows why the standard G5RV doesn't work well on 30m, 17m,
and 10m. If you want 30m operation, shorten the matching
section to about 20.5 feet. If you want 17m operation,
lengthen the matching section to about 37 feet. EZNEC
says that will give you a 50 ohm SWR of ~3:1 on 30m and
~2:1 on 17m. When I was running a G5RV, I had pluggable
lengths of ladder-line so I could vary the length of the
matching section from 20 feet to 36 feet for good
performance on all HF bands. Somebody (I forget who) used
remote controlled relays to accomplish the "tuning".
