For installation, you will need some items not supplied with the antenna installation kit:
•
A 6'-8' rigid mast or other mounting pipe between 1" and 1.5" outside diameter is convenient
for a preliminary test of resonant frequencies. Suitable materials include TV mast sections,
galvanized iron pipe, or heavy duty rigid conduit.
•
Quality low-loss 50-Ohm coax with a PL-259 from antenna to transmitter.
•
An Antenna Analyzer (MFJ-259B or similar), or SWR meter and transceiver
SAFETY PRECAUTIONS:
WARNING! You can be killed if the antenna, feedline, or the equipment used to install the
antenna accidentally contacts any utility lines. Never install an antenna near power lines!
