Posted: 06 Apr 2019 01:46 AM PDT https://forums.qrz.com/index.php?thr...baluns.653132/ " G'day all, just an update. Although the hybrid balun effected a great improvement, there was still a 'trace' of breakthrough so I tried another approach to see if I could obtain any further improvement....and I did! I used possibly the oldest technique around that of a wire quarter wave (and unconnected at the distant end) counterpoise cut for 40 m, the only really affected band. All breakthrough is now gone and all other bands are clean! Regards, Felix vk4fuq." So you completely fixed the problem with a quarter wave counter poise. Now we don't know if your hybrid balun was even needed. /////////////////////////////////////////// IC7300 and Hustler- BTV Posted: 05 Apr 2019 08:16 PM PDT https://forums.qrz.com/index.php?thr...er-btv.653241/ /////////////////////////////////////////// 75 Meter Bowtie with 60 Meter Coupled Resonator Posted: 05 Apr 2019 06:56 PM PDT https://forums.qrz.com/index.php?thr...onator.653130/ /////////////////////////////////////////// 6M beam height Posted: 05 Apr 2019 06:18 PM PDT https://forums.qrz.com/index.php?thr...height.653139/ /////////////////////////////////////////// Using a Fan or Bowtie Dipole to Cover 75/80 Meters Posted: 05 Apr 2019 06:11 PM PDT https://forums.qrz.com/index.php?thr...meters.641530/ /////////////////////////////////////////// Putting up R8- very challenging site!
