I have two flag rx ants and I was looking at the DHDL and DK6ED Double Loop System V2 and wondering if twisting my Flag rx ants into Bowties would improve the forward pattern and make them narrower w

Hi Mike, Funny you should ask that. A few months ago (September) I was looking at building a smaller size DHDL using 4Nec2, and there were a few things I saw that I thought needed improvement (I saw

Mike and Gang, It was this project (terminated bowtie) that got me looking into the KD9SV 994 x5 preamp a few months ago (I published some info on this preamp a few months ago). I think the KD9SV 994

Hi Mike and Don The DHDL as well as few other antennas, has a hidden component. The bottom wire parallel to the ground is a transmission line, actually, any antenna parallel to the ground is a transm

What kind of improvement in performance is observed by providing a better ground, JC? And, where would a ground wire (counterpoise?) be connected with the DHDL antenna system? Thanks and 73, Nick VE7

Hi Nick The wire will reduce loss on the transmission line given a better match and phase. In practice you can see change on the SWR and front back. If you have a good ground you probably won't see a

So, is the ground wire just left "floating", JC? No electrical connection to the antenna itself? Thanks and 73, Nick VE7DXR The wire will reduce loss on the transmission line given a better match and

Hi Nick I would say grounded both ends, don't need to be connected to the antenna itself, right. JC --Original Message-- From: Topband [mailto:topband-bounces@contesting.com] On Behalf Of Nick Hall-P
