Now that I have the resonant frequency of 2.278 MHz for my 68' tower.
What should the design frequency be for 160 Meters?
I have plugged 1.8 and 1.9 MHz into the formula for computing electrical length
and it comes out to 71 and 75 degrees respectively.
What is the next step here? Do I need to work on adding more top loading to the
tower to make the electrical length longer?
John
