Comet antennas


Base station verticals installed in high wind speed areas must be guyed.
Please don't force coaxial cable through walls (especially brick walls).
Please do not over-tighten any antenna screws or apply any glue.
Most Comet products ordered from us ship same/next day!
Prices are confirmed for antennas currently in stock.
Freighting or mailing of antennas is at extra cost.
Prices are subject to change without notice or
obligation due to exchange rate variations.
Limited stock of some Comet products.

Please don't instantly assume a new antenna is faulty, as <0.1% of
new antennas (<0.01% for Japanese antennas) are faulty from new!
Antenna faults are actually due to the installation ~80% of the time!

Where possible, please ensure coaxial cable lengths are in multiples
of a 1/2-wavelength (not in odd multiples of 1/4-wave lengths) on
every band, taking into account the coaxial cable's velocity factor.

We don't recommend mounting antennas >1m long on heavy vehicles!
We don't recommend mounting >1m long antennas on diesel vehicles.

PLEASE connect each section of multi-section VHF/UHF
 verticals' thin inner brass tube to the next section's thin
inner brass tube to ensure the antenna works properly!!

Please order by phone; 02 9688 4301/9636 9060/9896 8972,
 by email; radioandrews@hotmail.com or by mail;
