- Hello, I'm getting ready for the next CQWW SSB contest and I'm working in phasing 2 1/4 wave verticals for 75 meters and all simulations shows that best gain is obtained with 135 degrees phasing, but

- Joe, Why wouldn't you just add half of a 1/4 wave to a 1/4 wave? 90 degrees plus 43 degrees - 135 degrees. Rex - K1HI Merrimack --Original Message-- From: towertalk-bounces@contesting.com [mailto:tow

- Exactly Rex. It gets interesting if he's cutting the cables for electrical length instead of by physical length. If he's doing electrical length by looking for a point where they're (n+1)/4 wavelengt

- Oops! That should have read 90 degrees plus 45 degrees = 135 degrees. We're talking electrical length here, not physical length - but you already took care of that issue by using the velocity factor.

- Don't forget, the phase change in a cable is not equal to the electrical length of that cable if the SWR is not unity. You will need to calculate the necessary electrical length of the cable carefull

- know how to obtain 90 degrees is easy lines, which can but 135 is not as and one 1/4 wave but 135 degrees The delay of a transmission line is equal to the electrical length **only** when: 1.) The li
