I just might try it in a few weeks since better weather isn't too far away. Good tip about making sure the test is on more than one band. I wouldn't think it would be of much use at LF, but MF through 30 mhz would definitely be in order. I have better antennas for vhf and higher. rayb Well, Ray, th...

Very good Andrew. Well, it was just an idea I had that seemed to have a possiblility of working. That's how we advance the state of the art... come up with an idea and test it. Thanks for your reply. Your work saves someone from spending time and physical effort that won't produce the desired resul...

Hello, I just found this forum, as well as the info on the Sula antenna. Looking over the four pages of info on this post, it seems to be a very good "all around" antenna for swl'ing, as well as it having the benefit of only one null instead of the usual loop dual null. Ok, I'm going to b...

just a short note about how to route the coax feeding the SULA; the image below shows the effect of routing the coax outside the SULA or inside it (through the center), as you can easily see, routing the coax toward the center (second image from top) heavily changes the pattern, the backside "n...

Jock, any update regarding outdoor antennas ?

I obviously like it to bits! :) No, seriously, it's not having any severe highpass/reduced sensitivity issues typical for ham transceivers on MW/LW and it has all the nice tools one would want in a MW DX radio (particularly passband tuning and notch filter), being an SDR and showing me faint carrie...

hmmm... sounds like you had some wild fun

as for the CTL, did you consider changing the size of the sides ? I mean, for example, making the vertical size 1/2 of the horizontal (or the other way around) while keeping the same total perimeter

Welcome to the forum, qrp-gaijin! Hope you guys tell me when it's time to charge my little dremel tool. :mrgreen: ~20dB more gain / less losses at little more than 1/2 the size of the SULA sounds pretty intriguing, even though the overall coverage seems to be pretty small (7-21Mhz?). ...check if it...

forgot (and OT) do you know what happened to Jim's ham forum (the radio board) ? I know you were a member there, and there were a lot of cool folks, but then, it went suddenly "poof" <sigh>
