New Antenna Mast and Antennas ZS6EMS on 2/4/15
I thought I would drop you a quick note - - the best antenna that I built a number of years ago was a 10 meter mono-band Yagi, 3 elements, 12 foot boom from the details and plans provided in the 1974 ARRL Antenna Handbook.

When 10 meters was open, it worked great with my Kenwood TS-520, 200 watt rig.

Later I added a Hy-Gain TH3 Thunderbird, which I still have, but have it stored since I lost my Patio space for the tower.

Currently I am experimenting with a two-wire Yagi on 17 meters - just not sure it was build correctly - picked up the idea from the QST article by Marcus Hansen, VE7CA.

I think you will enjoy experimenting.

Please disregard my question - - upon searching the web a little further, I found the answer, possibly, but could damage the traps.

Thunderbird MkIII Tribander on 17 Meters with Antenna Tuner K0JMD on 1/4/15
Gentlemen - -

I am getting ready to put my Thunderbird Mark III tri-band back up after having cleaned & serviced it.

I have been working 17 meters with a 2 wire dipole/wire yagi in the trees.

Is it possible to use the tri-band antenna on 17 meters by employing an antenna tuner, or will the traps and element lengths on 15 & 20 meters interact making it impossible.

Thank you,
K0JMD
