[Elecraft] KX3 Field Ant. for 80/40/30

[Brian Hunt]

For several years I've been using a 33 ft wire and a pair of small 
tapped loading coils to get  an EFHW vertical resonant on 20m. 30m and 
40m.  It's fed with a link coupled tuned tank circuit consisting of a 
coil on a 1 inch powdered iron toroid and an air variable capacitor.  
The link consists of 1-6 switch selected turns which gives a wide range 
of impedance transformation.  Antenna is supported with a 33 ft MFJ 
fiberglass mast.  Easy to set up and tune.  I do have to haul the wire 
down to change the taps and retune for a band change.  Used with a K1 or 
KX2, the internal ATU is usually in bypass.
