Howdy Guys,
First post so take it easy with me.
I’ve recently got the bug to get back into cb’s after a very long time. I got my original antenna i used back in the late 80s early 90s. This antenna has been sitting outside all these years behind an old pigeon cage, so you can imagine the state it is in. It was originally purchased from Delta base in Thornbury, the antenna is all dismantled and from memory was 27 foot in length, is there a way to work out it’s wavelength? I need to get it cleaned up and assembled, but not sure on what height it needs be as it’s split in sections.
Thanks
caesar

just re-measured the antenna from top to bottom and it’s exactly 26.2 feet. Is it possible that it’s a .64 wave and I’m measuring it from the wrong spot (.64 should be around 23 feet I think).

with some googling I have worked it out, its actually 1/2 wave over 1/4 wave.

When you say 1/2 over 1/4 what decides the WL? Is there a trap or coil between the two sections?
A photo would be good -you can upload some from the tag at the bottom of the reply post box on the LHS.
Also what are you going to run into it with? A CB? OR….

I’ll try get a photo this weekend. I’m hoping to use it for 10/11 metres.

It’s been a long time, been busy with family/babies, so all this cb stuff went on hold.
Finally was able to take some pics of the antenna. (don’t mock my huge mast )
