Hi all, Thanks for leads, and thoughts. Sure is a lot to know, for me. Have always been very weal in ant. theory. Stay in touch, Bob Here I am ... or better said here we (the forum community) are, feel free to post questions and discuss doubts :D A last note, as Thomas knows (yeah, I think I "...

Here's an idea

Nice work Andrew! I'm beginning to think that an EFRW is a great general purpose antenna, so long as you have a tuner. I have a 35.5/17 EFRW that does very well for me, but I think that the longer the antenna and radiator, the better. My current antenna project is a travel EFRW using a pair of slin...

Greetings I wonder if anyone has used the Diamond hf-20cl mobile antenna as a POTA antenna with a ground spike or tripod elevated antenna? I would like to discuss or get ideas for ground radials or ground screen for using the antenna a a quick install field antenna? It's a great antenna, center loa...

Nice work. With regards to both EFRW & EFHW antennas, does raising the feedpoint/transformer height above ground make a difference in impedance or efficiency? I'm planning on installing a 132ft EFHW at home, hoping to get the midpoint & far end at 30+ feet. I've been wondering if it will ma...

Being curious, as I am :D and since the idea has been whirling in my head for some time now, I decided to run a little "experiment" regarding the (not so) "random" antennas, for such a purpose I created a model in 4NEC2 describing a somewhat typical "portable random" se...

I've been playing around with some EFHW antennas in the backyard. 1/2 W radiator and counterpoise straight to BNC binding post on the KX3. I'll probably wind myself a 9:1xformer. Also bringing 25' of RG316. A note, for an EFHW you'll need at least a 49:1, the 9:1 ratio is ok for an EFRW, the idea i...
