Re: Need help with Wellbrook Loop & SDRplay/SDRuno

One more note, the higher end preselector has been in the works on his website for several years. If you want a solution now, either go for the other one that's already available or some other solution.

Re: Delta loop antenna - advice please...

Given your lack of space, you might want to try a vertical inverted loop.

I built one about 5 years ago and it...
