K7WA's "Tenna Dipper"
by Jim Hadlock, K7WA
Yes, I used a 10 turn pot (it cost nearly as much as the Tenna Dipper Kit!) - the pot works very smoothly and makes the Dipper easy to tune.
The plastic case has a battery access panel which I use to access the DIP Switch and Hi/Lo jumper to change bands.
used the Tenna Dipper on the recent Washington Salmon Run to tune my mobile
and portable antennas - it worked great! I have a Force12 40-XK vertical dipole
which is a great antenna, but requires some tuning to get dialed in on each
band - the Tenna Dipper does an excellent job of finding resonance and letting
me know whether the antenna is above or below the desired frequency.
