Tony,
You have to keep in mind the current surge there until the heater
warms up. The colder the heater is, the more current it draws. I would
use a conductor with at least 750 cir mils per ampere. For 3 amperes,
that equals out to be about 16 AWG wire for the minimum.
In single layer RF choke service, #16 silicone-varnished (Type WT) Cu
wire will handle 20A. This type of wire is presently SOP in electric
motor shops.
Without doing any calculations, a higher inductance is indeed needed
for 160 meters. ...
