About the antenna tuner
CPVU8 is designed as using the antenna tuner makes the
best SWR. When operating, the auto antenna tuner of the
transceiver is ON. If the transceiver doesn’t have the
antenna tuner, use the antenna tuner. Check the antenna
tuner instruction when operating the antenna tuner.
Set the SWR meter between the transceiver and the
antenna tuner and check the SWR. If SWR is less than
2.0, you can operate the antenna tuner ‘Through”.
(However, if protection circuit of the transceiver is
operated and the transmitting is stopped automatically, it
is not so.)
CPVU8
Operation Instructions
Description
The CPVU8 is an eight-band ground plane antenna for
3.5/7/14/21/28/50/144/430MHz.
Since the CPVU8 is compact and light weight, it can
be used for temporary base station antenna.
The CPVU8 can be used at 144/430Mhz without any
adjustment. Other bands (3.5/7/14/21/28/50MHz) can
be tuned by sliding the each element.
-Note---------------------------------------------------------------
<<Installing the antenna>>
Don’t install on a rainy or windy day since it is dangerous.
Don’t attempt to install the antenna only by yourself.
Installing the antenna alone on the roof may lead you
dangerous accident. Always ask your friends for help
installing the antenna.
Don’t drop the antenna, tools and attachment when
installing the antenna in the height. Install the antenna
before assembling it on the ground.
