    Default ANTRON 99

    I just found an Antron 99 in my boneyard.

    Can I use it with 2m?

    I have a dual band 2m 70cm HT (FT60R)

    I found this about the anenna:
    * COVERS FAR ABOVE AND BELOW THE TRADITIONAL C.B. CHANNELS FOR EXPORT, COMMERCIAL AND 10 METER HAM BAND USE, INPUT 2000 WATTS P.E.P. * THE A99 IS A HALF WAVE OVER A QUARTER WAVE VARIBLE MUTUAL TRANSDUCTANCE TUNED ANTENNA * COMES IN THREE SECTIONS, EASY TO ASSEMBLE * ENTIRE ANTENNA RADIATES 9.9 DBI GAIN * LENGTH ASSEMBLED 17' 4". THIS IS A COMBINATION OF THE ANTENNA AND THE GROUND PLANE KIT.

    Not efficiently. People do however run these with a tuner between 20 meters and 6 meters.

    Consider making yourself a quarter-wave, ground plane, vertical instead.
    Many new hams use these as their first antennas.

    Use welding rod and an SO-239 connector.


    Or make a J pole:

    The A99 or Antron 99 are designed for 11 meters with a wide bandwidth for CB and CB freebanding. It also can work well with 10 meters. If you had a good 2 meter tuner, you could tune the A99 for 2 meters, but the effectiveness on 2 meters would be pretty poor at best. I tried it a long time ago, and a simple home brew 2m dipole blew the A99 away. Don't waste your time with it on 2M.

    Try it and find out. I'd say it will work terribly.

    Nope, and I would not waste my time with it for VHF service.
    Thousands of base CB antennas have been sent to the boneyard/jankyard over the past 2 decades --
    a majority of these can work on 10 and 12 meters -- with no/little adjustment.


    For a 2 meter antenna, look for these Jewels in the Junkyard/Boneyard:

    1. Copper pipe 1/2" -- Build a J-pole, numerous plans on Internet.
    2. Broken automotive antennas - 1/4-wave 2-meter whip OR if long enough can be made into a 5/8-wave vertical with a small homemade coil at base.
    Several plans in 1970 magazines: Ham Radio, CQ, QST, 73.
    I built an adjustable 5-8 wave 2-meter antenna with a radio Shack repalcement auto antenna, small brass rod, PVC caps, a coil of wire, a PL-259, and some epoxy. I still have this antenna built while in college (no $$)!!
    3. Some of the original CB antennas made by Antenna Specialists (and others) can be converted to 5/8-wave 2-mete rmobile antennas. Again, several articles in the 1970s magazines for these retrofits of CB surplus.
    4. Broken TV antennas a a good source for aluminum to use for 2-meter yagi antennas.

    Default Thanks for the response

    When I searched the site before it seemed that "no" would be the case but found no direct statement. So I asked the question directly.

    I'll hang onto the Antron 99 for use as a CB base station or trade it if any Hams want it. I don't have plans for a CB base station at the house right now.

    I am working on this project

    Two scanner antennas, NMO mount
    Two 2M 70cm dual band antennas - Diamond SG7000, 7500 or 7900, NMO mount.
    One 102" CB whip with spring side mount
    and 4 NMO connectors with bare wire

    Yep as others have said NO WAY the A-99 even if you trimmed the top whip to nothing it would be the worst 2 meter antenna you could have. I use a A-99 trimmed for 10 meter and have a 1.2.1 SWR on 10 it workes very well.

    Don't waste this ant on CB ! It will work fine for ten or twelve meter ham operation, Tech licensees have SSB privelages on ten Meters.
    This antenna will not work as well as a 20 inch ground plane ant on 2 M!

    Default Ok

    Sounds like I'm keeping it so when I get a radio that has 10m I'm ready to go.

    Upgrade to general class, and you can use this antenna on 15, 12 and 10 meters. Pray that the solar activity improves (sun spots return) in next few years -- for better propogation on those bands.
