[Elecraft] Antennas for K1 Field Use

[Dave, G4AON]

There are no advantages in using commercial antennas out portable. A 
fishing pole for support and a lightweight dipole, doublet, end fed wire 
or ground plane will work better than most other simple antennas and the 
cost is minimal. The K1 built-in ATU has a fairly limited tuning range 
and will only tune some doublets and end fed wires... especially on 
80m/40m. I've had success across 40/30/20/15 metres with a 51 foot 
doublet and 32 foot of lightweight 300 Ohm ribbon fed via a balun on a 
couple of feet of coax. On 80/40 metres with a longer doublet, it can 
prove troublesome to tune with the standard ATU, however by adding a 
couple of capacitors the tuning range on the lower bands can be 
extended, see: http://www.astromag.co.uk/pdfs/g4aon_kat1_mods.pdf
