Now You Need To Install The Top Whip
Whip Length versus Frequency Coverage
3 ft. --4.0 MHz to 32.0 MHz
4 ft.--3.7 MHz to 30.0 MHz
5 ft. --3.4 MHz to 28.0 MHz
6 ft. --3.2 MHz to 26.0 MHz
8 ft. --2.8 MHz to 20.0 MHz
10 ft.--2.5 MHz to 18.0 MHz
12 ft. --2.3 MHz to 15.0 MHz
CH-1 -- Capacitance Hat
Hat only -- 3.5 MHz to 30.0 MHz
Hat with 3 ft. whip -- 3.0 MHz to 25.0 MHz
Hat with 6 ft. whip -- 2.7 MHz to 21.0 MHz
Our standard whip is 6 ft. long; it can be cut to any length for the coverage you need.
Keep in mind that the longer your whip is the better the performance will be on the
lower bands, however you will loose your upper frequencies with the longer whip. As
and example, if your main frequencies are 17 meters thru 80 meters then the
capacitance hat plus the 6 ft. whip are a powerful combination.
Initial Tune Up
For the initial tune up a SWR analyzer is nice to have if you have access to one. If not, make
all your adjustments with low power. Now, lower your antenna until it reaches the end stop
and go to 10 meters (or your highest frequency depending on whip length) and check your
SWR, it should be low. Next, you can go to 15 meters and raise the antenna until you get
a SWR dip there. Then 20, then so on.
Keep in mind that 10-20 meters are close together. If the SWR doesn't go below 1.5 on
these bands the ground is probably too far away, remember the ground needs to be less
than 1 foot from the base of the antenna.
Do not try to twist or turn the bug shield on the outside
of the antenna, this is designed not to turn.
