I am looking for an antenna to put on my Relm RPV599A Plus Handheld radio it needs to be the 5/8 wave or whatever it is that is long that gets the best reception like they use on wildfires across the country they are very long like 2.5 feet or so long. the problem is the connector on my radio is a SMA Male so the antenna needs the have the female part and I have searched and searched and called places with no luck so I thought I would throw it out here to you all.. Thank you for any help. Riley.
