Phil is right that you do not hear many people using a quad these days.

>From 1972 until 1983, I ran a Hy-Gain 2 element tri-band quad that they 
called the Hy-Quad.

The wire elements and plastic insulators finally broke to the point 
that I had to look at rebuilding it. Since I had a Mosley TA33 JR in 
storage, I opted to scrap the quad, and gave it to a missionary friend 
who did rebuild it for only 15 meters.

While I worked the world with the Mosley, there was no comparison 
between that antenna and the 2 element quad.

When using the quad, if the world didn't beat a path to my door, that 
quad would go out and drag the world in off the street.

Mosley also made a 2 element quad at the time I ran the Hy-Gain. My 
friend across town had their quad, but couldn't keep it operational for 
more than a few months at a time.

I believe Cubex is still around, but I may be wrong about that. If they 
are not, I don't know who makes a full size quad commercially for any 
band or band combination.

Some of the best fun I ever had was during 2 field day operations where 
the club I was with at the time ran a full size 2 element quad on 40 meters.

The bottom was about 10 feet off the ground, but that thing would 
scream. When we had worked everything we could hear on the east coast, 
four guys would pull up the anchor ropes, walk the antenna around to a 
different direction, then drive the anchor pegs back into the ground. 
Those were the days!
