[Elecraft] UPDATE KPA1500 on 160M

[Lyn Norstad]

Adrian -

Comment on the BD #4116 "hybrid" balun:  

It's a combination 4:1 impedance transformer and 1:1 current balun all in one unit.

I am using that on my 360' center fed EDZ (with 160' true ladder line and 15' coax) and it combines to give my KPA/KAT500 a match of 1.2:1 or less (mostly less) SWR across all bands 160-6m.

Ok on that. I have good success with true OCF (not windom) antennas and 
Balun Designs 4:1 current baluns in the past.

These days I just use apex high delta loops with direct feed via a 
lmr240 multi-wound toroid choke at feedpoint for great results.

Bottom corner fed (vertically polarised), so feed-line length and losses 
are kept minimal . I find this type of antenna very quiet,

and neighbour friendly in all respects.


It would have been interesting to see how a 4116 performed on yours.
