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

[Fred Jensen]

My HOA-Stealth antenna is the "80-10 EF" from myantennas.com  It is 
strung on electric fence insulators along the top of the wooden fence, 
about 1.8 meters high.  It has a 90 deg bend in it about 1/3 of the way 
down from the transformer.  It actually works 160-10 with my K3/100 + 
KAT3.  It works surprisingly well, so much so that I bought a second to 
take on county expeditions in the 7QP contest.  I took First in Pershing 
County this year with ~350 CW-only Q's.  While that is also "Last in 
Pershing County," that is not indicated on the certificate. [:-)  Next 
year I may be First in Lander County, who knows?
