The PAL-OCF2006 covers 20-17-15-12-10 and 6 meters in a length of 32 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 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 32 feet (7 feet and 25 feet sides).

SWR TECH NOTE:The SWR graphs shown are specific to the conditions listed including antenna height, configuration (flat top, inverted V, inverted L, etc.) and direction, feed line length and type, geographic location and soil condition, calibration and accuracy of SWR instruments used. Your SWR measurements will probably be different and manufacturer takes no responsibility or liability for these differences beyond the purchase price of the antenna.
A simple ferrite ring filter on the DC power line can help suppress the RFI noise affecting the victim device or keep the DC power cord from acting as an antenna and radiating RFI into other victim devices. This kit is also useful on laptop computer supplies, routers, cable modems, wireless phone charges, etc.
Installation is quick and easy: Just wrap the DC power cord through the center of the ring filter as many times as you can and reinstall. For best results with long DC power lines, use one at the ring filter at the wall wart end (to prevent the wall wart power supply from using the DC line as an antenna) and another at the DC plug end (to prevent the electronics in the powered device from using the DC power cord as an antenna). Typical installation is shown below:
The filter suppresses RFI in from .1-100 MHz. Inside diameter is 3/4 inch/19 mm.
Since most households and office environments have multiple wall warts we offer the Wall Wart RFI Filter kit in bulk quantity packages.
Known RFI Generators include Roku/Sling-TV power adapter - Interference heard in the AM broadcast band and harmonics. Also many ethernet Cable/DSL modems, cell phone chargers, computer power adapters have the same issue: using the AC or DC side of the power supply as a radiating antenna. RFI solution is to use a linear power supply, change adapters or wall wart ferrite filters
