Can anyone point me to a good site for construction a 5/8 wave 2M antenna???
I tried home-brewing one already with poor results .... a conductor up a piece of PVC .... same conductor wound into a coil at the bottome connected in series to the center of the coax. 4 1/4 wave radials connected to outer conductor. I believe there's a project in the ARRL Handbook which shows how to convert a Radio Shack CB whip antenna to a 2-meter 5/8-wave - it has the details for the matching coil that is required. http://www.arrl.org/tis/info/pdf/8009022.pdf has another QST article which shows how to construct one from scratch, using a technique that doesn't require a matching coil (the matching inductor is made from a stub). I haven't tried either of these myself. With regard to the version you made - did you account for the loading effect of the PVC when you measured and trimmed the length of your radiator? -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
