When a balun is NOT used with unbalanced coax connected to a balanced dipole antenna, the opposite phasing relationship still exists between the center conductor and the inside of the coax shield, but there is an additional conductor formed by the outside of the coax shield, which can radiate RF from the coax and back toward the transmitter because the phasing is now not equal in both directions.
The 1/4 wavelength Pawsey Stub adds an additional path for the signal from the center conductor back to the coax shield to cancel the RF on the outside of the coax shield. The simpler solution is to use a regular 1:1 balun or even a coil of coax of specific length. See PDF

All amateur operators are welcomed to check in. N6USO repeater system is right at the top of Sunset Ridge peak, just over 5,300 feet above the city of La Verne, Claremont and Pomona, CA. So those with beams should point to just north of Claremont. It is a high level machine with great coverage and should afford us all of the benefits.

IMPORTANT REQUEST BELOW
HAM RADIO HISTORY REQUEST: I'm looking for some historical information about ham radio in LA in 1971. In particular, HF links going to San Jose.
It seems like a strange request, but the younger hams these days don't work HF and I know back then there were a lot of Nets people would check in to (I don't know if they exist still or if they have declined over time or are as active as in the 60s and 70s). Personally, I lack a lot of HF knowledge since I became a ham to do AMSAT stuff. Any information, including possible ARES/MARS work in the LA and southern California to San Jose area would be great.
