I purchased two antennas from Gulf Alpha and waited many months for
delivery from the manufacturer.  The craftsmanship and assembly is
exceptional.  However, I have changed my station and will not be
putting these antennas into service.

These antennas have been assembled but have never seen "the light of
day."  I have pictures available upon request.  I will disassemble and
pack as neatly as they were sent to me.

The VHF antenna is a circularly polarized 5x5.  The UHF antenna is a
circularly polarized 8x8.

Detailed specifications are below.

For sale only as a pair.  $400 FIRM shipped CONUS.  I will ship
international however the price will be adjusted to compensate for
tax, duty, and additional handing.  Willing to deliver anywhere
between Dallas and Houston, Texas on I-45 at same price assembled.
