[TowerTalk] Need manual for EF-180S

[Grant Saviers]

As others said, the EF180x design is swaged tubes with steep tapers and 
thus pretty useless as a template for a wire antenna. (and hard to 
model)  I would measure the coil inductance, probably all that matters 
since F12 likely has the SRF in an ok place.  Then plug L into EZNEC and 
find a placement that resonates with your total wire length.  Might be a 
good project for AutoEZ, especially if you include the tower model.
