[Elecraft] Feeding a Random length wire with the KAT2 ATU

[David Gropper]

Adding my $0.02 worth...

There is a very nice table in Les Moxons' book "HF Antennas
for All Locations".
It is Fig 4.37 and shows lengths that are non-resonant
dependant on the bands you want for your basic Inverted-L
antenna assuming you don't mind radiation from the feeder !!.

For the Non-WARC bands, other good choices are 58, 76, 96, and
109 feet. This assumes you are using capacitive matching
which, of  course the KAT1/2 tuners can easily handle. (Thanks
Elecraft chappies!)

If using a "Pi" type tuner (C-L-C) then resonant lengths can
be used - even an overall length of 133 ft, as an inverted-L,
is capable of some good contacts on 160M even as low as 20 ft
off the ground. Not the best but it will give you some
contacts. (Personal experience!!)

Usual disclaimers....
