PAL-OCF4010 Multi-Band Off-Center Fed Antenna
The PAL-OCF4010 covers 40-30-20-17-15-12-10 and 6 meters in a length of 66
feet. In most cases, no antenna tuner is needed and switching bands is as
easy as changing the band on the radio. Super convenient and quick – great
for contest operation! Choose 500, 1500 or 5000 watts PEP power levels.
Uses hybrid balun containing wide band 4:1 transformer + 1:1 common mode
feed line choke to keep all your power on the antenna and off the feed line
coax outer conductor!
Unlike Buckmaster OCF antennas (at twice the price, and no WARC band or 15
Meter operation), you can transmit and receive on 6, 12, 15 and 17 meters
with our OCF - Better engineering and lower price - only from Palomar
Engineers!
Also much quieter than end fed half wave antennas!
INSTALLATION
For best results support balun 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 internal or external antenna tuner may be required or
some bands to bring SWR at end of feed line to acceptable levels. Overall
length is 66 feet (11 feet and 55 feet sides).
