Yeah. Try this, should just be a couple of inches...

You can hide it in a baseball cap and wear it at the top of top of tall
buildings and make contacts on your handheld...

Warmest regards,
John

Oh yeah. Another "odd ball" design idea--construct an EH Antenna on a ball
point pen... and used as in the method mentioned above... grin

Warmest regards,

Dave listed zsro-dBd gain antennas which are nearly omnidirectional.
Yes, a dipole has nulls at its ends but it isn`t sharply directional.

The next logical step may be to try a directional antenna such as the
Yagi-Uda. It has only one feedpoint and is simple but it lets you choose
the direction od your communications.

There are many examples but a good one can be found in Kraus` 3rd
edition of "Antennas" on page 248. It has anout 12 dBi (10 dBd) gain and
can be fed by 300-ohm twinlead.

With a Yagi, you can choose your direction of communications while
turning a deaf ear n other directions.

Best regards, Richard Harrison, KB5WZI

How about a "Juicy Two"?
