External antennas

I'm trying to learn more about the use and added benefits of
supplementary/directional antennas for Lectro 200 and 210. The objective is
to minimize hits either from fringe interferences and/or for distance. For
the most the antennas would not be used as a stationary position but for
ENG. The sound operator would have to hold and direct the antenna (s). I
know that Lectro make a few models.

Directional antennas are generally used for stationery receivers. Hand
holding and aiming a big paddle, Yagi or Log Periodic antenna on a stick
would be far too difficult while moving around. Especially in an ENG
situation when you are moving amongst other people and navigating
obstacles while walking. Not to mention the wind gusts!

When you see wireless cameras, the transmitters have omnidirectional
antennas while the receive antennas are on stands or tripods.

What you can do to increase gain, is to elevate the antennas, and keep
the away from and above other objects. When transmitters are belt
mounted, the RF energy is absorbed by the body. Sweat increases this
effect. Receivers should be fitted into a mixer bag such that the
antennas are above everything else and in the front of the bag (not
between your body and the mixer). They should also be as far apart as
possible. The antennas should be the correct length for the frequency in
use, and on the Lectro's, one should be vertical, and one horizontal.
