I would like to share some of my experience with small flags'. The directivity is the same for a large chance in frequency but the gain increase with size. As a reference NX4D started with a single f

Hi JC, Thanks for posting all the great info. In my article I mentioned I normally use 20 dB of gain with my portable flag, but on 80 and 160 I sometimes use more gain. I just double checked, and sur

I said I'm glad I have the available extra gain that the DX Engineering preamp offers whereas most receivers would not benefit from it. I should have said that having the extra gain should not be det

Anti-phased double loops are also a good way to approach an RDF of 10dB on 2200m (137kHz).  1/2lambda is nearly 3600ft.... so broadside arrays and beverages are usually a non-starter... close spaced
