[Elecraft] wire antennas

[Craig Rairdin]

I happen to have pictures of just such a beast at
http://www.craigr.com/coppermine/thumbnails.php?album=35. It's cut for
40/20/10 meters and works nicely on 15 of course. The KAT100 tuner makes it
work on the WARC bands and even on 80m though not very well.

Yes, you CAN put multiple dipoles on one feedline.
It's commonly done in the government and/or commercial
world.  It's often referred to as a "fan dipole".  The feedline
can be either coax or open wire/TV twinlead.

Picture two telephone poles (or towers) with the support
points for the individual dipoles several feet apart vertically
along the two poles/towers.

Such an arrangement is sometimes seen at a National Guard
armory or Civil Defense center.

The dipoles -DO- interact and will need length adjustment,
one at a time
