Feeding a 4 bay vertical folded dipole
"N4aeq" wrote in message
ups.com... I need to build a 4 bay folded dipole like the one use on vhf/uhf repeaters. The folded dipole is easy enough to figure out but how do you get the 4 - 300ohm dipoles to combine to one 50ohm feedline, I have looked close as i can at these and there is no combiner but it looks like maybe some coax phasing stubs or lengths of coax inside the antenna support mask? The ARRL book, FM and Repeaters (1970s) included information on building a "phasing harness". Kevin Custer, K3KKC has some of this information at his Repeater Builder web site: http://www.repeater-builder.com/rbti...seddipole.html w9gb |
