    I came across a loaded antenna that has a mount I'm not familiar with. I have searched Google and Yahoo for the this mount and have found nothing that I can confirm will work. If anyone knows what the mount is I'd really appreciate some information. I am thinking of making a 220Mhz antenna out of it if I can find a mount for it. And before you say its cheaper and easier to just buy an antenna, let me say that I have the the time, and desire to learn how to make it work. Yes I can buy a 220 antenna for about $30.00, but where is the satisfaction in learning something new, and gaining a new skill.

    A gutted SO239 will screw into the antenna. and the pin from a PL259 will find in the center connector snugly. This is an odd design that I have never seen before.
    Any help will be appreciated.

    Thank you,

    Appears to be a UHF-RP (reverse polarity), which is a rare bird not usually found on the open market. I've seen these in use a few times in custom OEM products where the manufacturer wanted to assure a user cannot possibly exchange their antenna for any other type, and the antenna and mount are sold together.

    Thanks for the info, you wouldn't happen to know the OEM name or have a part number I can lookup?

    I am thinking about making an adapter for this, but I'd like to get more info on the actual connector.. and possibly buy a mount.

    What you have is an old style Antenna Specialist mount that was very popular in the 60's and 70's, for "base loaded" antennas from CB up to about 175MHz. It will indeed fit over an SO239, has the same thread pattern.

    Anyone have any idea where I can obtain a mount/connector for this antenna??

    Even an old one with bad coax will work for me. I'd like to avoid fabbing one if I can... It will be challenge enough to rewind it for 220.

    I probably have some laying around somewhere. I'll have to look in my warehouse of radio stuff.

    It looks like a variation on the Antenna Specialists mount that many "CB" mobile antennas used. I may have one among my antenna "junque" box.

    Sorry I had to go out of town last week haven't look at my email. At all this week.

    If you have a mount that would be outstanding.

    Let me know if you have one, and how much.

    Thanks to everyone who replied.
