Product Details
Brand: Palomar Engineers
Freq Range (MHz):: 14-54 Mhz
Power (PEP watts):: 500/1500/5000 watts digital
Length (ft):: 32

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.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise.  Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.

We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener.  Maximize the distance from the camera to the openers may also help.  Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.

Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
