The Base Antenna Tuner has been designed for operating with most End-fed Long Wire and Whip Antenna systems in fixed land station applications.

The Tuned Long Wire Antenna is ideal for field crews who require an antenna that can be quickly and easily erected at temporary camp sites or similar locations. It may also be used in permanent installations where space is limited. The Antenna is supplied as a kit for installation and includes halyards, pulley, earth wire and strap, and a complete set of installation instructions.

Tuned Long Wire Antenna
The Tuned Long Wire Antenna may be used for either temporary or permanent fixed station installations, and is suitable for multi-frequency operation with most Transceiver systems with a Base Antenna Tuner.

Guyed Vertical Whip Antenna
The Guyed Vertical Whip Antenna is designed for installation on buildings or open ground and is suitable for most Transceivers operating with a Base Antenna Tuner.
