Recommendations:
Scenario 1:
Occasional
recreational use of computer in more remote areas
where the broadband card is marginal and user has no general requirement for a longer
external antenna.
Recommendation: Purchase CD1225- best value small size
450mm high antenna. Gain is 3 dbi. This antenna can be disassembled for easy transport and stowage. Works with all aircards except Minimax.
Bundled with both laptop bracket and desktop base.
Scenario 2:
Cabin cruisers or sailboats where a laptop is brought on board
occasionally by a business person. Boat is operating in fringe areas such as Pittwater or
Broken Bay and operator wishes to have "the best possible business communications"
on board.
Recommendation 1:
Purchase SW1496. This is a 5 dbi antenna with
a magnetic base. Useful in temporary locations and will not blow over in
the wind. This
antenna requires a metal ground plane (such as a car roof) or metal ground plate for optimum
radiation performance. This antenna can be used without the ground plate, but
performance will be reduced somewhat depending on the environmental conditions.
Bundled with the ground plate. Can also be mounted to a car roof.
Recommendation 2:
Purchase CD1298. This is a standalone 5dbi
450mm fibreglass rod antenna that mounts onto a boats structure using clamps or
brackets. Requires pole mount to suit which are available at
chandleries.
Recommendation 3: Purchase CD1250. This
5 dbi antenna bundled with a desktop base. Not suitable for laptop
bracket.
Scenario 3:
Sailing boats or trawlers cruising near the coast:
CD1298 Permanent Mount 5 dbi Marine Antenna.
Mount as high up as possible. Special cable and fittings for this antenna
is sold by the metre at $8 metre complete.
Scenario 4:
Trawlers operating at sea well away from visual
coast sightings:
Recommendation: COL1799 (no photo, but similar to
CD1298)
Almost 2 metres long but with 9 dbi of gain.
(If installed on sailing boat under way, performance will reduce. Most
effective when boat at anchor or when antennae is in vertical position.
Special cable and fittings for this antenna is sold by the metre at $8 metre
complete.
