[QUOTE="user 12139, post: 616706, member: 12139"] 468 / MHz = 1/2 wave length (ft) Measure and cut a length of wire to your half wave length answer Cut the wire in half and then feed each piece of wire with your coax, + one side, - the other you now have a half wave dipole which can be run vertical, horizontal or even at 45deg... whatever you like the higher you can get it the better Ideally any antenna you build you should check the VSWR to be on the safe side, if ya don't and your SWR is out you can cook your transmitter TX transistors! If propogation is good and your up on top of a hill, with 10 watts on 27Mhz you can work the world! CQ CQ CQ.. this is BigL looking for a Big Gal, pshshshhhhh, phshshhhhhhhh..... Oh Hi there honey, show us ya money :lol: [/QUOTE]
