GAP should resume exporting soon...

Base station verticals installed in high wind speed areas should be guyed.
Please don't force coaxial cable through walls (especially brick walls).

Please note that sea freight, air freight and air courier charges regarding
shipments from the USA have increased dramatically since late 2022!!

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.

TITAN-DX is an 8-band centre-fed HF vertical antenna with swr of <2:1 across ALL of the 10m, 12m, 15m, 17m, 20m, 30m and 40m bands.

Swr is <2:1 across 100kHz of 80m band. Factory pre-tuned to 3.6MHz centre frequency for Australia, at our request. Length is 7.6m (25').

Weight is 11.3kg. The TITAN-DX requires NO radials. The first 2.4m (8') section is double wall tubing, then triple wall at the mast mount.

The antenna's four rigid counterpoises are 2m (80") long. Note that Titan's cardboard box is 2.63m long! Rated to accept 1.5kw SSB.

Includes a special PL-259 plug which suits the antenna's coax cable.

An optional double female coaxial joiner (e.g. SO-238, not SO-239)
will be required if you wish to plug your base station coaxial cable's plug (e.g. a PL-259) into the antenna's included special PL-259 plug.

Alternatively, you could fit an in-line SO-239 socket onto your existing base station coaxial cable and plug that into the antenna's PL-259.

Guying above the GAP centre insulator with non-conductive guy wires, such as 6mm diameter polyester rope, is recommended.

Base station verticals installed in high wind areas should be guyed!

In most instances an antenna tuner is not required!

Eight-band 80m~2m vertical base antenna

(80-40-20-15-12-10-6-2m bands)

Type Price $(AUD)

CHALLENGER-DX is the first production elevated-feed vertical antenna to cover 80m, 40m, 20m, 15m, 12m, 10m, 6m, and 2m bands.

Swr is <2:1 across ALL of 40m, 20m, 15m, 12m, 6m and 2m. Swr is <2:1 over 130kHz of the 80m band and <2:1 over 1MHz of the 10m band. Gain is 6~8dB on the 2m band, according to CQ magazine.

Length is 9.6m (31.5'). Weight is 8.1kg. The CHALLENGER-DX may be ground mounted or roof mounted. A ground mount is provided. Fits into an area of 3m x 4m.

Includes a special PL-259 plug which suits the antenna's coax cable.

An optional double female coaxial joiner (e.g. SO-238, not SO-239)
will be required if you wish to plug your base station coaxial cable's plug (e.g. a PL-259) into the antenna's included special PL-259 plug.

Alternatively, you could fit an in-line SO-239 socket onto your existing base station coaxial cable and plug that into the antenna's PL-259.

Requires three 7.6m (25') long ground radials.

Guying above the GAP centre insulator with strong non-conductive guy wires is recommended!

Sold out!

GAP should resume exporting soon...

160m is an integral part of this antenna!
It's not just an "add-on" 160m kit, hi!

Type Price $(AUD)

VOYAGER-DX is a dedicated elevated-feed 160m, 80m, 40m, 20m vertical antenna. On 160m, the bandwidth is >90kHz at the 2:1 swr points. The swr is <2:1 across ALL of the 80m, 40m and 20m bands.

The VOYAGER-DX employs a capacitance hat with a circular ring to electrically lengthen the antenna. Length is 13.7m (45'). Weight 13.6kg.

Requires a minimum of three 17.3m (57') long ground radials and four guy anchor points spaced 7.6m (25') from base mount. Aluminium pivot and guy brackets supplied. Requires two sets of guy ropes. No tuning or matching is normally required. This is a relatively "quiet" vertical antenna.

Includes a special PL-259 plug which suits the antenna's coax cable.

An optional double female coaxial joiner (e.g. SO-238, not SO-239)
will be required if you wish to plug your base station coaxial cable's plug (e.g. a PL-259) into the antenna's included special PL-259 plug.

Alternatively, you could fit an in-line SO-239 socket onto your existing base station coaxial cable and plug that into the antenna's PL-259.

GAP MONO-BAND HF vertical antennas All GAP MONO HF vertical antenna pricing is subject to change without notice or obligation due to exchange rate variations. Single band 40m, 30m, 20m, 17m, 15m, 12m or 10m antennas Place your order for GAP MONO vertical antennas...
Type	Price $(AUD)
GAP MONO vertical antennas are single band antennas which function as asymmetrically fed vertical dipoles. They provide an swr of <2:1 across the entire specified band and will accept up to 1.5kW of RF. GAP MONO verticals are supplied with a three-wire counterpoise and simple drop-in ground mount. The counterpoise length is 80% of the antenna's length. E.g. on 40m, the GAP MONO antenna itself is 31 ft. (9.45m) long and its supplied counterpoise is 25 ft. (7.6m) long. GAP MONO verticals include a feed-line that is an electrical half-wave, cut for the centre of the band of operation. Includes special PL-259 plug. An optional double female coaxial joiner (e.g. SO-238, not SO-239) will be required if you wish to plug your base station coaxial cable's plug (e.g. a PL-259) into the antenna's included special PL-259 plug. Alternatively, you could fit an in-line SO-239 socket onto your existing base station coaxial cable and plug that into the antenna's PL-259. Base station verticals installed in high wind areas should be guyed! In virtually all instances an antenna tuner is not required! ALL GAP MONO verticals require ordering!
