Is this a loading coil?

... Hi, I'm not really sure what all of that means. I'm learning about antennas, and I've been doing a lot of reading on the web until I can get a copy of the ARRL Antenna book. I'm learning the terminology and the other day read a thread about loading coils. I had no idea what that was, so I went in search of an explanation. So, when I saw the radio shop selling antennas with funny looking coils I wondered if that's what a loading coil looked like. But I had expected a loading coil to be at the bottom of the antenna, these looked like they might be in the middle of the antenna. Does that even work? BTW, I enjoy reading old threads from Roy and Cecil. A ton of great information there. I have learned alot, and have much more to learn. I want to try to make a 2 meter yagi (3 elements) this weekend and experiment a little. Maybe I can finally hit that repeater 30 miles away. ;-) Jim -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHM8yWQuDJiZ/QrH0RAuVCAJ9IVGKLg1XtBrsOcNFmI9jsTO1R3gCg05dW 56RRsfoNjTeiHMxWvymiiZQ= =4zuW -----END PGP SIGNATURE----- Well, that page deals with bootleg/illegal cb equipment. However, years ago I bought a 1KW+ dave made amp which had been modified a bit and covered 40-10m, it worked quite well, I drove it with a small homemade xmitter I bought at a swap. In addition to the material you are getting from the arrl material--loads of amateurs have put together web pages dealing with antennas/amps/equip. Most provide an email address and most are only too glad to advise/help. And of course, you will find everyone here interested in antennas and can share good advice, and you are quite correct--Cecil, Roy and others have a LOT of good knowledge on amateur antennas ... Loading coils can be placed anywhere along the length of an antenna, for varying effects on radiation pattern, matching requirements, etc. EZNEC, Roys little program makes it a snap on graphing what to expect ... Keep reading/studying, you'll get hooked and grab a license! Regards, JS |
