I also added radials to a Ringo Ranger and found it to improve the operation on an old Progress Line tube type 2 M repeater I built back in the '70s. I built them from aluminum ground wire and clamped them to the base of the antenna. I found that it improved the operation of the repeater quite a bit.
I observed that some Ringo Ranger base station installations worked just fine and some did not, and suspected that the feedline decoupling mentioned already was a problem. The radials helped to keep antenna currents off the outside of the feedline and improved the operation. 73 - Jim W5ZIT --- On Thu, 10/2/08, wd8chl <[EMAIL PROTECTED]> wrote: From: wd8chl <[EMAIL PROTECTED]> Subject: Re: [Repeater-Builder] Re: Antenna recommendations 220 To: Repeater-Builder@yahoogroups.com Date: Thursday, October 2, 2008, 8:53 AM Our solution was to add radials from a junk Stationmaster at the base of the antenna itself, a few inches below the 'loading' coil. Made a HUGE difference, even in a non-duplex app. ____
