the 2:1 frequency limits. The 2:1 bandwidth on 20 meters should be 250 kHz minimum. Find the center of the

band.

4) If you desire to move the center of a band you can by loosening the stainless steel hose clamp on the Super

"C" mast and changing the position of the basket relative to the collector grid. Raising the basket 1" should increase

the center frequency approximately 70 KHZ. To lower the frequency lower the basket. Yes lower the basket!

Continue the measurement process on 17m, 15m, 12m and 10 meters remember to switch both the selector knob

on the Super "C" switch box as well as your transceiver.

5) Using an antenna tuner when the vswr is less than 2:1 is permitted. Remember an antenna tuner does not tune

the antenna but stops the reflected R.F. from reaching the transmitter and causing a power reduction in the

transmitter's output.
