Shrouded Yagi Antennas for the 1800 MHz Band
DESCRIPTION
Series of three shrouded yagi antennas with 6–15 dBd gain.
Covers the 1800 MHz DCS-1800/PCN band (1710 – 1880 MHz).
Can be used for both vertical and horizontal polarisation.
H-plane beam widths 24° to 80° and E-plane beam widths 23°to 60°
depending on model.
A sturdy glass reinforced plastic shroud ensures effective protection
against the weather.
All metal parts are DC grounded for noise reduction and lightning
protection.
Materials carefully chosen for minimum electrolytic corrosion and
intermodulation.
Supplied with fixed Norstell clamp (48.5 mm dia.)
Reliable and robust design for optimum performance and long lifetime.
