Hi Bob,

For the record, I have a doublet that is in the inverted vee 
configuration, cut to 100 feet per side. It is feed via open wire (~600 
Ohm) parallel line (nominally balanced) down the tower and to the eaves, 
with a shorter run of window line (~400 Ohms) under the eves to a DXE 
1:1 current balun (I prefer to call it a choke) at the back of the 
house. There is then an eight foot run of RG213 coax into the 
basement-located shack to an Elecraft KAT500 auto tuner. I use this on 
all bands from 80m to 20m. It can tune up through 6m, but I have other 
antennas for those bands. And I shunt feed my tower for 160m ops.

I don't normally use a 4:1 or 1:4 balun, and was only responding to your 
question about semantics in my previous post. Elecraft sells a nice 
low-power balun that is switchable as 1:1 or 4:1. I have used it for 
field/portable ops, but it's usually set to 1:1 for the antennas I use 
(44' or 88' doublet).

Gus
