Pocket size antennas are fine for BC reception but for weak amateur CW signals somewhat suspect. g3kev ----- Original Message ----- From: "John Rabson" To: Sent: Thursday, December 22, 2011 11:02 AM Subject: Re: LF: Re: LF/MF X-Band Request Ben, On receive it is the SNR that matters. It is a good idea to have a loop (preferably rotatable) as well as a long wire, so you can choose which gives better reception. I have found a 2x 2 metre air-cored loop very effective for receive on 137. 73 John F5VLF On 22 Dec 2011, at 11:19CET, mal hamilton wrote: > Hi Ben > RX antennas seem to be the problem for most.
