2MXP20 XPOL notes
The idea is that I will run the coax along these braces to the power dividers. .(By 20"* Vel Factor of cable). Hit my first real problem today.

Bicycle Antenna
Its proper length is dependent on the velocity factor of the coax used (see table below). Factor 0.66, Vel. Factor 0.80. A to B, 11.25 in. 13.5 in.

2 Meter Turnstile Antenna
Then feed the turnstile antenna with a 1/2 wavelength 4:1 coaxial balun. Vel. Factor 0.66, Vel. Factor 0.78. 26.73 in. 31.59. in.

Coaxial Cable
Vel. of Propagation: Lower number is generally for solid dielectric and higher number for foam Velocity Factor of Propagation (Vp) Through Coaxial Cable.

Screwdriver Antennas
B.F. Ansell,III, KI0AR, http://home.att.net/~bfa3/sai.html A matching transformer using 75 ohm coax.. 68 inches at .66 vel factor = 103 inches free space.

AMfone
Use the formula 492/ freq * .66 (coax vel factor) to get the 1/2 wave balun length in feet. Here's how you connect it: You have two ends of an 11' 4" piece.

Technical question re antenna - aus.radio.amateur.misc | Google Groups
Using a coax balun, consisting of a half > wavelength of coax (X vel factor .66 typically). Should this balun be > made of 50 ohm or 75 ohm coax and why?
