Hi Gang,
I have just installed a DX-77, the Hy-Gain 7-band trap vertical.
5 of the 7 bands tuned just fine, however, 12m and 17m show no resonance
whatsoever. A check of the antenna with my MFJ-259B shows resonance for
these two bands as follows
12m - 24.6 mhz
17m - 17.7 mhz
Since both of these resonant frequencies are below the bands, I need to raise
the resonance by a few hundred khz on each band. Here is the problem: the
only adjustment to the traps discussed in the instructions lowers, not
raises, resonant frequency.
Can anyone suggest a solution, or give me a hint as to why these two bands
are so far out of the bands? FYI, the out-of-the-box resonance on the other
5 bands was within the band limits, and YES, I have double/triple/quanruple
checked all measurements.
Tnx, Geo...
