NOTE:
Even of these are mostly tower-mountable systems, they can be installed on shorter poles for less effort and expense.

#7,098,861
Similar to the one immediately below:

Similar to the ones above and below:

#2,380,333
This one has arc-shaped extensions added to it as a transmitter aerial for directed studio-to-transmitter linked applications:

#2,324,462
Similar to the one immediately above:

http://www.google.com/patents?id=XIN6AAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q=&f=false


NOTE
These others will be more general in design that the first four, but will still concern pole mounted systems in for the most part:

#6,921,042
Fig. 2 is a Caduceus coil:
NOTE: Caduceus coils can reduce battery charge times significantly if they're carefully built.

#5,065,164
Vertical system with loading coils:

#2,985,878
Alternating counterwound sections of a pole mounted aerial(fig. 4):

#2,945,227
This system can also be mounted vertically:

#1,708,515
This one has a coil inductor in the middle of a horizontal mounted arrangement(can be vertical0:

#2,941,207
This is important.  I asserted elsewhere in Overunity that this inventive arrangement can simulate a much longer aerial, whether vertically or horizontally mounted:

#1,314,095
Similar to #1,967,881 but with tuned coils.  Fig. 2 has a spark gap---the first I've ever seen on a transmitting system:

#3,448,440
A combination of a spiral coil and a Caduceus coil in one:

#1,689,337
Figs. 7 & 8 are the most relavent.  Experimentation can prove if either one is better than the other:

Hi Lee.

I think broad band Bow Tie Antenna are very efficient if arrayed and directed. from 3cm on up to 1 meter band.

Hi Jerry,
Yes, I see.  These types of antennae are sometimes used to direct signals from remote TV reporter's trucks to the main transmitting station, I think.
