I have an old (ca. 1975) HyGain TH6DXX and an older (ca.
1965) HyGain 402B(A). The antennas are not complete in that
the boom of the 402 is missing as are the boom extensions of
the TH6. All plastic parts died during 25 years of storage
in a Texas attic (this includes trap end caps) and the
linear loading wire of the 402, although present, is
somewhat less than linear. That said, these might be of
some use to someone with the same (or similar) antennas as
spare parts, etc. If you live in range of Fort Worth
and are interested in either or both of these antennas, give
me a call (at work): 817-777-6266 or reply to this email.
The antennas are free.
