Andrews Communications - 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!!

Comet handheld/portable transceiver antennas
Type	Price $(AUD)
NEW MODEL PACKAGE NOW COVERS TEN (10) BANDS!! Model; COMET HFJ-350MTOYBX (TOYBX = Toybox) Ideal for IC-705, FT-817/818, etc., portable MF+HF+6m radios... Covers 1.8MHz to 50MHz amateur bands (160m to 6m bands)! This new PORTABLE 10-band antenna package is 1.92m long. Amateur bands covered; 160m, 80m, 40m, 30m, 20m, 17m, 15m, 12m, 10m & 6m. RF power ratings; 160m; 50W average/80m; 75W SSB pep/ 40m~6m bands; 100W SSB pep. This portable 10-band telescopic whip antenna package comprises four (4) main sections. One section, the "base coil", is fitted with an integrated PL-259. This "base coil" is a MULTI-BAND tapped coil to which the included wander lead would be fitted for selecting the 10MHz, 14MHz, 18MHz/21MHz, 28MHz or 50MHz band. Package includes 1.8Mhz/160m and 3.5MHz/80m coils! The included telescopic whip antenna always fits on top of the antenna once the appropriate coil & tapping is selected for the frequency/band desired. The telescopic whip allows fine frequency adjustment on all above bands. A long (minimum length of 9m) counterpoise multi-stranded plastic coated wire should be fitted to the earth lug that is located on the outside (earth) of the antenna's PL-259. We recommend an earth stake be permanently fitted to the counterpoise wire to enable better RF earthing/grounding. The HFJ-350MTOYBX has an integrated PL-259 plug, multiple taps and wander lead with banana plug fitted. The HFJ-350MTOYBX's telescopic whip enables tuning to all amateur MF/HF bands and the 6m band. Rated to accept RF up to 50W average on 160m (1.8MHz/1.9MHz), 75W SSB pep maximum on 80m (3.5MHz) and up to 100W SSB pep maximum on the 40m to 6m (7~50MHz) amateur bands. Change bands by selecting the appropriate coil, then plug one end of the wander lead's banana plug into the "common terminal" and the other end into the desired band tap & adjust the telescopic whip's length for lowest SWR. It is recommended to use BOTH an antenna tuner and counterpoise with this antenna if you wish to obtain the best possible results. A counterpoise (earth) wire of at least 9m in length should be fitted to the antenna's earth lug that is fitted to the antenna's PL-259 plug. This is a 1.92m long, 1/4-wave multi-tapped, base-loaded antenna. Note; this antenna is NOT suitable for mobile vehicular operation. COMET HFJ-350MTOYBX 160m~6m portable kit set NOT recommended or suitable for mobile operation!	$369.00 PLENTY IN STOCK! NEW MODEL!!
