Do not try to twist or turn the bug shield on the
outside of the antenna, this is designed not to
turn.
Now You Need To Install The Top Whip
Whip Length versus Frequency Coverage
32 in. -- 9.0 MHz to 58.0 MHz
4 ft. --8.0 MHz to 49.0 MHz
5 ft. - 7.0 MHz to 37.0 MHz
6 ft. - 6.5 MHz to 32.0 MHz
8 ft. 5.5 MHz to 23.0 MHz
10 ft. - 5.0 MHz to 21.0 MHz
12 ft. -- 4.5 MHz to 19.0 MHz
CH-1- Capacitance Hat
Hat only -- 7.0 MHz to 45.0 MHz
Hat with 3 ft. whip 6.5 MHz to 27.0 MHz
Hat with 6 ft. whip -- 5.3 MHz to 25.0 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
an example, if your main frequencies are 15 meters thru 60 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.
