There are a couple of antennas which don't fit into any category in particu-
lar, but which should be mentioned because when used with a Smartuner,
they will deliver spectacular results.

This is our recommended antenna to be carried aboard all types of vessels.
This is because when a wind strong enough to damage a boat occurs, it is
easy to fly a kite and this may lift fifty to one hundred feet of antenna wire.
For good emergency communications, you will only need 30-70 feet of
antenna and a strongly built (Mylar or nylon) kite.
Remember that when a mast comes down, you have easy access to the high
voltage feedline which may be secured to a kite antenna. Offshore power
boats can use this antenna as well, since 10-20 knot winds are almost always
available when underway at sea.

Over the course of nearly 30 years of HF, SGC equipment has been used
everywhere from camelback in the desert to Antarctic expeditions. Along
the way we have collected a number of tips to get maximum system perfor-
mance from your radio system when you are operating in a tactical or disas-
ter situation. These tips, by the way, also apply when you go camping or are
involved in amateur radio Field Day activities:

Note: The counterpoise may be underwater if installed on a
beach or from a vessel at sea. If an underwater counterpoise is
used, tuning may change with tide changes in shallow waters.
This type of antenna has been run for hours in tropical trade
winds with excellent results.
