PAL-OCF4010 Antenna
OCF antennas are very convenient as they will allow multiple bands of operation with a simple wire antenna
which is fed off center. This antenna will work on 40-20-17-15-12-10 and 6 meters.
Installation
For best results support center at 30+ feet and ends over 15 feet. Angle of feed each side must be great than 45
degrees or 120 – 180 degrees total between each side preferred. Any length of 50 ohm feed line ok but longer
feed lines over 50 feet may show reduced SWR on some bands due to losses in feed line and soil conductivity,
nearby objects, etc.
Due to local ground conditions, antenna height and feed line length, SWR may vary from samples shown and an
antenna tuner may be required or some bands or portions of bands to bring SWR at end of feed line to
acceptable levels. Use a good quality 52 ohm cable adequate for the power level of your station.
The PAL-OCF4010-500, -1500, -5000 are rated for 500, 1500, 5000 (respectively) watts PEP ICAS at a
maximum 25% duty cycle. Digital modes are approximately 50% of PEP ratings at 50% duty cycle depending
upon band.
