Roger G3XBM’s Amateur Radio Blog: 10m with simple antennas


See on Scoop.itKH6JRM’s Amateur Radio Blog

There is little doubt that when 10m is in the doldrums a beam and QRO would probably be helpful. Every bit of power would help. An HF beam is unlikely to add more than 5-6dB gain (1 S point) so when the band is in good …

Russ Roberts‘s insight:

Another great, to-the-point article from 10 meter expert Roger (G3XBM).  Like Roger, I’ve always believed simple antennas, properly designed and  built, can reap big rewards on problematic bands such as 10 meters.  I still have a few converted CB antennas that work very well on 10 meters once they were  cut to the proper length, had an adequate radial system, and were  elevated approximately 1/2 wavelength above ground.  I agree with Roger that "there are very few times when QRO really matters.  It may help, but it is much more fun with QRP…"  He adds that "QRP can be great fun, especially with simple homemade antennas."  If you prefer a vertical antenna for 10 meters, why not build a simple ground plane antenna using a converted CB whip antenna (108 inches/274.32 cm before trimming) in conjunction with four sloping radials cut to the same length?  You should get a good match for any 50 ohm coaxial cable feed line.  Wire antennas can be educational, cheap, and fun to use.  Aloha de Russ (KH6JRM).
