CODAN Multi-wire Broadband Dipole HF Antenna code 463

I have experienced install this antenna at Swiss Bel Hotel Banda Aceh For EUEOM
(European Union Election Observation Mission to ACEH 2007)
It's perfect and powerful.

==========================================
CODAN 463 series Multi-wire Broadband Dipole HF Antenna is a 3-wire terminated folded dipole HF antenna designed for broadband operation in fixed stations. It is available in multiple power levels up to 1 kW. The antenna can be mounted horizontally between two support systems, or as an inverted “V” using a single central support mast.

KEY FEATURES

Durability
CODAN C463 series HF antenna is made from lightweight, weatherproof materials designed to withstand extreme environmental conditions and wind speeds greater than 200 km/hr.

The wire elements are constructed of high quality, corrosion resistant stainless steel, with balun and load housings, and insulators made from UV resistant, durable moulded plastic.

Performance
Due to the antenna’s optimum performance over a wide HF range, an antenna tuner is not required — minimising cost and setup requirements.

Antenna performance is very similar in both horizontal and inverted "V" configurations.

The inverted V configuration provides a good overall solution for most base station applications with the added benefit of only requiring a single mast for installation.

For long range operation, the horizontal configuration is recommended.

Easy to install
CODAN HF antenna is supplied completely assembled and ready for erection with an inverted V mounting arm and detailed erection instructions.
