2. Clip the Wander Lead [D] "Alligator Clip" onto the coil (making sure you have a good electrical connection

with the "Alligator Clip" and the Coil) according to the tuning chart below and, if necessary, and adjust the

telescoping antenna length (see Tuning Chart below).

3. Check the SWR using an accurate meter and, if necessary, adjust the Wander Lead placement or

telescoping antenna length for best SWR (down for lower frequency and up for higher frequency).

Tuning Chart

Band (Frequency)

40-Meters (7 MHz)

30-Meters (10 MHz)

20-Meters (14 MHz)

17-Meters (18 MHz)

15-Meters (21 MHz)

12-Meters (24 MHz)

10-Meters (28 MHz)

TIP: All values are only approximate – your antenna's tuning requirements may vary slightly. You may consider

placing stickers (or placards) on the coil rings to mark each band or tuning placements of your specific antenna.

IMPORTANT: Each time you change the frequency or band on your transceiver, it is important that, BEFORE

TRANSMITTING, you re-tune the antenna to the new operating frequency using the steps outlined above.

Operating Tips

•

Choose a good clear, open field to operate from

(the further away from trees and other structures

the better the radiation efficiency of the antenna)

•

Please note that the "Tuning Chart" information is

only approximate tuning locations for the "Wander

Lead" and lengths for the telescoping antenna –

each antenna varies slightly and placement/length

for each band may vary

•

Place a rock over each end of the Ground

Radials/Counterpoise Wires to secure in place

•

Keep Tuning Wander Lead wire from touching the

tuning coil – only the "Alligator Clip" should be

touching the tuning coil

•

A void operating in windy conditions or moving the

coil unnecessarily to keep SWR "sway" to a

minimum

PLEASE NOTE: It may be possible to

operate this antenna on bands other than those it

was originally designed for (i.e. 80-meters [4

MHz], 6-meters [50 MHz], 2-meters [144 MHz],

222 MHz, 440 MHz and others).

This might be accomplished by adjusting the

extended length of the Telescoping Whip

Antenna, trying various Tuning Coil positions,

adjusting length of the Counterpoise/Radial

Wires and/or by simply using an antenna tuner.

However, absolutely no guarantee or warranty is

made or implied for operation outside the

designed operating limits and the operator

assumes all risks and responsibilities while

operating outside the designed limits of the

antenna.
