Hi, All
I'm installing an end-fire pair of phased Beverages here and decided
to actually measure the velocity factor of my coax (RG-6, foam
dielectric) before cutting the phasing line. Measured out a given
length near 50 feet, known to the nearest inch, shorted the end and
swept for the first Z minimum with my trusty Auteck RF-1. Made half
a dozen or more Z measurements and then double checked the length of
the cable. Every time I get the same results: VF=84%. This just
seems a tad high to me, especially when 75% is the published value
for RG-6, though I know the VF of foam cable is higher. Could the
frequency display on the RF-1 be off, or is this value typical?
Anyone else get similar results when checking this type of cable?
73,
Charles - K5ZK
