keep in mind that in order to get that mirrored reading from the antennas feed-point in a run of coax it needs to be a electrical half wavelength (or multiple) and knowing the velocity factor and frequency is critical in calculating that length . just using a physical half wavelength doesn't mirror the reading . and yes i agree using a single or multiple electrical half wave length of coax is cutting hairs and not necessary . however , the additional loss of having a few to several extra feet of coax on the CB band (this is the CB forum section) will never ever be noticed in the real world .

BTW once you go up or down one channel from that perfectly calculated electrical half wavelength it isn't perfect anymore . and the farther away you go the more error there is . IF someone wants to do it i'd suggest doing it on the channel you use the most .
