Default WTK: Shortwave Recommendations Antenna for IC-706MKII

I think it is more then obvious that you do not know what you are
talking about when it comes to antenna's.

The key to any antenna is LOCATION / LOCATION / LOCATION....

If you are in a crappy location, it is not going to work well...

If you are in a good location, the B & W 90 will out talk your Carolina
Windom or any other long wire antenna, due to the fact that antenna
tuners reduce the amount of power applied and they do not physically
tune the antenna, just the coax to the antenna. The only tuners that
works is the ones that are placed directly at the feed point of the
antenna, not something inside of the shack...

The B&W 90 on 20 meters acts kind of like a beam antenna, which exhibits
some forward gain - due to the nature of it's construction.
The one wire acts like a reflector while the other wire acts like a
driven element.


From someone that did not know about the ringo type antenna and what it took
to make it a halfwave, you make the statement that I don't know what I am
talking about when it comes to antennas.

Now you are saying that because the B&W has two wires it acts like a beam.
This is not correct at all.

A tuner will allow antennas to match the nominal 50 ohm output of a
transmitter to the antenna system that is not 50 ohms. You will loose about
5 to 10 percent of the power in a tuner. That crappy B&W burns up most of
its power in that big resistor in the middle of it.

The simple wire antennas while having gain in one direction will not have
gain in another direction. Unless you have specific stations to talk with,
the gain may be useless if it is in the wrong direction.
