Frequently asked questions about ARL530.1
Some common questions about the ARL530.1 HF log-periodic directional antenna 6–30 MHz:
What are the typical applications of the ARL530.1?
The ARL530.1 is a big size HF log-periodic directional antenna designed for
6–30 MHz long-distance and international radio links. It is typically used
for HF broadcast services, governmental and defence communication networks,
coastal and maritime HF links and other professional HF infrastructures where
high power and reliable coverage are required.
Which electrical performance does the ARL530.1 offer?
The ARL530.1 covers the 6–30 MHz band with a typical gain of
7 dB, VSWR ≤ 2.5 and 50 ohm
nominal impedance. It is rated for up to 2000 W RF power and uses a
7/8” connector, making it suitable for high power HF transmitters in
professional installations.
Which polarisation and radiation pattern does the ARL530.1 provide?
The ARL530.1 operates with horizontal polarisation. It offers a typical
E-plane beamwidth of about 30° and an H-plane beamwidth of about 90°,
providing a directional pattern suitable for long-distance HF links and controlled coverage
towards the target service area.
What mechanical characteristics and installation constraints should be considered?
The ARL530.1 has an overall length of about 18 m and a weight of
approximately 120 kg. It is mounted with 300 mm diameter clamps
on a suitable mast or tower. The antenna is built with aluminium, Teflon, iron and
stainless steel AISI 304, with all metal parts DC grounded, and requires a robust
support structure and professional installation to withstand wind and environmental loads.
