There's plenty of info on this forum and others about end-feds like the a99,
every so often the same kind of technobull keeps getting posted about a simple 1/2wave end-fed antenna,

a99 does not use the coax as a stub or counterpoise or whatever you call it in order to work or have good vswr, a99 is not 1/2 over 1/4wave any more than it has 9+db gain,

a99 does not need any mast or coax to be what it is a 1/2wave end-fed with enough metal below the feed-point for return currents & low vswr even when using a cordless analyser with no mast/coax involved,

not all mast or coax lengths cause cmc issues on the a99 but when they do you can fix it with isolation or sometimes just changing the length of your coax or mast..
