First Antenna, 1/2 wavelength 10m dipole

Hi All,

So, since this is about Ham Radio, you had to have guessed that there would be talk about various types of antenna.  I have a terrible dislike of spending money, so instead of buying my first antenna, I decided to build one instead.

As a newly minted Technician class Ham Radio Operator, the only HF bands that you have voice privileges on is the 10-meter band (28.3MHz - 28.5MHz).  You can operate CW on a few lower bands, but since I am still in the process of learning Morse Code  (CW), I decided to build an antenna for use where I can talk on voice (using what is called SSB or Single Side Band).

A dipole is a very basic antenna, and very easy to build.  Basically, you need some wire, and something to use as a feedline, such as coax or twinlead.

My Parts List:

  • 20' of stranded copper wire
  • 1 x 3/4" PVC "T" fitting
  • 2 x 2" pieces of 3/4" PVC pic as insulators
  • 20' of nylon rope
  • 100' of 300-Ohm twinlead from Radio Shack

Time to Completion:

  • One hour to measure, cut, solder, mess-up, re-do, and finish.
  • One additional hour to hang between two trees.

Here is a quick pic:

Once it was up in the air, I connected it to my radio via my tuner, and was talking to California, Idaho, Montana using SSB on 28.4MHz!

That it for this post, hope you enjoyed it!
