By way of observation, I do think there are better performing HT antennas out there, especially for two meters. The stock antenna works fine on 440, but the antenna from my Kenwood THF6 blows it away on 2 meters. While at the Milton, Florida ham fest last July, I bought the SMA equivalent of the PL258 barrel connector. This coupler is a female SMA connector on each end. It is about the size of a pencil eraser, so if you get one, screw it onto the end of an antenna, and leave it there. Otherwise, you will be constantly chasing it around until it gets itself lost. I tried it with the antenna from my Kenwood THF6, and was very surprised at the difference it made on 2 meters. I have also used it with the MFJ duel band antenna that is about 17 inches long. That works too, of course, but I don't want that for my primary antenna because of the length. Since there are better 2 meter/440 ducks out there than the Kenwood antenna, buy either the SMA connector that I mentioned, or the BNC to SMA male connector, and you will have lots of antenna options. I bought both connectors from Cedar City Sales, of Lebanon, TN. I think they were $5 each. Mike Duke, K5XU American Council of Blind Radio Amateurs
