[Boatanchors] Valiant on 160, Antenna Opinion

[K3PID]

I've been using a 220 ft center fed zep in the WØOXB (Lew McCoy )
configuration. That's center fed with 450 ohm ladder line to the edge of the
roof then a 4:1 current balun like the MFJ-912 (N9INN version) then 50 Ohm
coax into the schack. It loads nicely 160 thru 10 and even in the bottom of
the 6 meter band. Get it off the ground though! 45 ft minimum! Mine run
about 70 ft up. Great signal reports, generally if I can hear them on 160
thru 17, I can work them. Google WØOXB or LEW McCoy to get the facts.

I was just telling Mac WQ8U that I brought my Valiant off the backroom shelf
and back into the radio room after a serveral year absence.  I blew up the
Valant back then while trying to get on 160 meters with my 80 meter dipole,
450 ohm ladder feedline, Heath SA2060A.  I set her on the shelf never got
back to fixing her.

The Valiant is back and I'll start troubleshooting her.  I'm guessing that I
likely blew out some output coupling capacitors due to horrendous mismatches
while fidgeting with the 80 meter antenna on 160.

To that end, I'm thinking about adding as much wire to the antenna that I
can to get closer to 160.  Its currently an 80 meter dipole around 135', fed
with 450 ohm ladder line.  I use it as an allband antenna with the Johnson
KW Matchbox.   I might be able to add 30' to 40' to each end, resulting in
more like 200'.  While I realize it isn't 260', 200' is alot closer to 260'
than 135' is.  Then maybe the Heathkit SA2060A will have a better chance of
tuning.

Does this sound reasonable, anyone doing this, or am I terribly confused?
