Many thanks to SWLing Post<\/em> contributor, Eric McFadden (WD8RIF)<\/a>, who writes with the following question:<\/p>\n

A\u00a0request for assistance.<\/p>\n

After comparing the reception of the RSP2<\/a> and 1\/2 doublet to the reception of the County Comm GP-5 SSB<\/a> and its little external ferrite-bar, I’ve decided I probably want to make some sort of directional antenna to use on AMBC with the RSP2. A wire loop, perhaps, or some sort of ferrite-bar thing, that connects to the RSP2’s Hi-Z input.<\/p>\n

[Perhaps SWLing Post readers can suggest]\u00a0options and then I can get the needed bits at the 2017 Hamvention.<\/p><\/blockquote>\n

Post<\/em> readers:<\/strong> if you can offer Eric suggestions, or point him to antenna plans, please comment! I do believe he would rather build an antenna than simply buy one and he’s looking to permanently mount this antenna outdoors.<\/p>\n","protected":false},"excerpt":{"rendered":"
