    Description

    220 MHz
    Base Antenna – Ham Band
    This is a 220-225 MHz base antenna designed specifically for the 220 MHz ham band.
    It is a J-pole type design and thus does not need radials or a ground.
    I have my students build these in addition to our dual band and UHF antennas.
    I have been an instructor at the Univ. of California since 1998 (formally at Berkeley and now at Santa Cruz-Silicon Valley) teaching primarily graduate course in wireless communications.
    Each antenna is custom built and tuned to your requested frequency by me or my graduate students.
    For general HAM use, a center frequency of 223.5 (222-225MHz) MHz is adequate.
    You can also custom order for the 219-220 MHz band.
    There is no charge for custom tuning.
    Connector choices are SO-239 (aka female PL259)
    or N  ( extra) connector.
    We can send you a PDF copy of the numerous articles and patents we have on these antennas.

    This antenna is complete with exception of the 4 feet of ¾ inch Class 200 PVC pipe needed for the antenna.  Individual shipping of the 4 ft antenna is so we rather you go to Lowe’s (stock # 23990)  or Orchard Supply (stock # 648-5908) or Menard (SKU #6899684) and buy the PVC pipe for about .  If you cannot find the PVC pipe, I can ship the antenna with the PVC pipe.  Please email me if you need me to send the antenna with the PVC pipe.
    The antenna has a lifetime warranty.  Just return it and it will be either repaired or a new one sent to you or 100% refund (buyer choice, no questions asked).
    Please email me via ebay and I will gladly answer any questions.
