Assembly and Adjustment
①
Set the upper element in the upper part of the loading coil
and fasten the set screw temporally.
②
The element of HF6CL is adjusted to lower frequency of
amateur band at initial condition. Please check the
resonated frequency with SWR/power meter.
③
Calculate the difference between the resonated
frequency and the desired frequency after confirming the
resonated frequency. Referring to the below frequency
change amount, calculate the element adjustment
length. If the frequency is lower than the desired one, cut
the element. If the frequency is higher than the desired
one, set the element at higher position.
Frequency change amount: Approx. 75 KHz/cm
<<Attention>>
・
Do not touch the antenna during transmission to avoid
electrocuting.
・
Since VSWR of an HF antenna varies depending on
installation locations, be sure to adjust at the place where
the antenna is operated in practice.
・
Adjustment has to be take place at the place where is no
obstacles or power line, and where does not hinder other
cars and pedestrians.
・
Due to insufficient earth capacity correct adjustment can
not be performed at the place where has vast space
under the car such as on a bridge or in the multi-level
parking lot.
・
To avoid interfering other stations, adjustment has to be
performed with least RF power and shortest time as
possible.
<<Warning>>
・
Setscrew for the bracket must be connected to car body
directly to have electrical interconnection. VSWR cannot
be lowered if the bracket and car body are insulated.
・
VSWR may not be lowered if installing the antenna at
gutter mount or roof carrier where is away from car body.
・
The place mounted with antenna bracket may get the
rusty and make the rust-proof on it.
・
Be careful not to have the waters into the car from the
entrance of coaxial cable to the car.
・
Wire the coaxial cable without any problem when driving.
・
DonÕt install antenna, bracket and coaxial cable at the
place where is close to other wire, terminal box of the car;
otherwise, fatal accident should happen.
・
Fold over whip element structure
①
Loosen the lock nut and pull up when turned down.
②
When setting up, raise the antenna vertically, set the
element into the element holder, and fasten with lock nut.
<<Attentions>>
・
Don’t drive with the antenna turned down; otherwise, fatal
accident should happen.
・
In case the antenna stretches out from the car body when
turned down, detach the antenna otherwise, fatal
accident should happen.
・
When using the tiltable whip, pay attentions not to pinch
your fingers.
