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. 73 Lyn, W0LEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Adrian Sent: Wednesday, September 02, 2020 9:37 PM To: w5...@comcast.net; Elecraft Subject: Re: [Elecraft] UPDATE KPA1500 on 160M 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. On 3/9/20 11:37 am, w5...@comcast.net wrote: > 4114T was the BD Balun model #. I'm not putting down there product at > all.
