Tell us about yourself!
What is the impedance at the feed point at radio/tuner? I heard conflicting opinions some saying it will end up close to 50ohms others stating would be off and require a balun.Also in response to suggestion of air wound choke- these are only mildly effective at a very narrow freq range. Ferrites either snap on or other of proper mix will provide much higher resistance over a wider freq range. Most commercial all rf chokes use ferrites on coax in an enclosure w connectors for this reason.
Ihave been using WhoCrashed ffor over a decade. Far simpler than this method and takes care of any required downloads if they are needed as well.http://www.resplendence.com/whocrashed
