Ohh that's a loading coil alright, seen plenty of 'em at
cb-swap/meets/shows in the midwest. The shows used to be a lot more
open, now you have to know someone or be invited.

He should be warned, those BIG mobile amps draw a lot of amps and you'll
be into adding extra batteries in the trunk and alternators under the
hood! (think ambulance/swat-team/military vehicle industrial
alternators.)

Also, those BIG base amps can cause you to drop a new box into yer
house/shack to supply the power--above 5KW just gets too crazy, IMHO ...
and don't even think about it unless you have a place out in the boonies.

Anything above the smallest base amp with the big tubes is kinda
crazy--IMHO.

You want to run more power than that, think about starting up a real
am/fm broadcast station!

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. ;-)

The antennas in the ad are center loaded antennas. Some of them are made
very well, Im not sure of the ones in that particular ad. The ones of the
design you ar looking at are often connected with some very unrealistic hype
but for the most part they are a quality antennas at a reasonable price.
