Subject: 40 Meter Dipoles and DXing

Jack,

Just a quick observation on 40 meter DXing. I am using an inverted vee at
about 60 feet and it doesn't display any really detectable
directionality. For a while I had a second vee at 45 feet, oriented 90
degrees to the taller one, but I recut it for 30 meters after testing
didn't reveal any benefit from the second antenna. I doubt that even at 60
feet the vee has much of a low angle component to it, but it may not
matter. If you will concentrate on the sunrise and sunset periods to chase
low band DX, the arriving wave angles are rather high. Running a KW into
this antenna system snagged 200 countries on CW in just in the last two
winter seasons alone. This may get easier as we come down off of this
sunspot peak, and more DX gets chased down to the lower frequencies.

I think before I put up a rotable dipole for 40 at a low height,
particularly if it is something like a shorty forty, I would use a full
sized wire antenna. Depending on your local tree type and count, you might
be able to get it up a bit higher than something with a rotator under it.

No matter what you decide, have fun with it.

Very 73,

Hank
