The lenght of the 75 Ohm cable should be an electrical 1/4 wave lenght.
This is free air wave lenght multiplied with the velocity factor of 75 ohm
cable (typical .66).
In meters this should give (300/14.2)*.66 wich should give 3.49 meters.


Hi guys. I just bought a Butternut HF9V9 vertical. I notice it calls for a
length of 75 ohm coax to match - how long should this be?


I'm just curious: how do you figure out a 1/4 wavelength on a nine-band
antenna?

73 .... WA7AA
