If you are looking for:

  • A wire antenna with about 4.5db gain over a half wave dipole
  • An antenna that is markedly quieter on receive..generally as quiet as a loop or better
  • An antenna you can hide from that little old lady in the HOA yet not compromise in size and performance...with antennas size does matter!
  • Something you can mount up high, close to the ground, or even laying ON the ground!!
  • It doesn't compromise by trying to be a multi-band antenna and working marginally on all bands - it works exceptionally well on the band it's made for.
  • Handles static discharges as needed all along the antenna in lightning and sand storms.
  • Can run full legal power on the band it's designed for. (note: if installing it along eaves or fence lines power should be lowered to safe exposure levels)

The CCD antenna is like nothing else on the market.  And it just might be that bit of magic you've been looking for.

CCD means Controlled Current Distribution.  This is a full wave dipole (or long wire) that has a series of capacitors mounted along the wire on specially designed boards.  The idea being that the current distribution along the entire antenna wire is relatively constant.

This antenna is well worth looking into.  We have a full set of articles that have appeared over the years that shows the advantages of the CCD.  The disadvantage has always been that they are a total pain to build.  Now, for the first time, you can have one made that is commercial quality and built to last!

"Bottom line is it works very well, and the reception is great! I made a contact with England, right after I put it up! - Scotty, KE7NCO"

Consider this.  Our radios use oscillators, filters, mixers and all sorts of other things to produce and fine tune our incoming and outgoing signals.  Why shouldn't we fine tune the antennas for less noise and better distribution of the power?  This is why the CCD is a nice break from traditional antennas. 

Q: What is it?
A: It's a full wave dipole that has anywhere from 24 to 48 capacitors evenly spaced along the wire.

Q: What does 'controlled current distribution' mean?
A: Imagine an antenna that has a fairly even amount of current across the entire antenna, not just the middle or the ends.  And end effect is pretty much eliminated as well as high voltage arcing at the ends of the antennas.

Q: What does this evening out of current on the antenna do for me?
A: Let's see, there are a lot of interesting properties of the CCD...

  • Height above ground is not important.  Actually works laying ON the ground.  Of course, like any antenna, up is good!
  • It is very quiet because of the caps keeping static on the wire down.
  • It doesn't interact with metal or ground around it.  Run it close to a chain link fence or flag pole and see little or no change in resonance.  Transmission pattern may change a bit.  This is a perfect LARGE antenna that can be put under eaves, along block fences, and other places to avoid the HOA Gestapo.

Check out the various magazine article collection on CCDs (you'll see it's not just us who think these are

"The CCD delivers on receive like no other antenna! - Jim, KD5AY"

 pretty darned dynamic antennas!)

Take a look at the coverage charts

See how we build them! (yeah, messy shop, but great antennas come out of it!)

Below is a peek at the capacitors as they are on the antenna.  These are VERY strong antennas!
