OUTBACKER ANTENNA OUTREACH 500
Your OUTBACKER‚ antenna can be installed on cars, trucks, RVs and for fixed operation (condos, apartments, etc.). As with any antenna system, there are no specific rules to follow. However, here are some helpful suggestions:
Mount as high as possible, and as far away from other vertical metal areas as possible. If mounting in a condo, use a metal balcony rail where possible, or three-inch wide copper foil (minimum 20 ft. length for counterpoise).
The optimum mounting location for any mobile, is dead center of the vehicle roof. However, since this is not usually practical for most HF antennas, mount your antenna on the drivers side trunk of the vehicle to avoid tree limbs, etc.
Use high-grade 52-ohm RG-58cu coax, or similar, with at least 95% shield. Marine grade coax is the best. Do not use foam coax as it will deform in heat and absorb moisture. Avoid solid center conductor-type coax as it breaks easily. DO NOT SPLICE THIS "RUN" OF COAX. It should be a single, unbroken length from transceiver to antenna mount. Use Coax Seal to protect cable where its wires separate at mount.
A solid electrical ground is an absolute necessity for proper and successful antenna performance. This is the most important yet often overlooked step in all mobiling antenna installations.
DO NOT IGNORE THIS STEP AND DO NOT ASSUME THE
NEGATIVE LEAD OF A POWER CABLE GIVES AN
ADEQUATE GROUND CONNECTION. IT DOES NOT!
Install a wide ground strap between a bolt connected to your autos frame and the ground lug on your HF radio. A round/frame bolt is usually located behind your autos dash. Another ground/frame bolt is also used to secure the front seats in place (look under seat for shiny bolt). A large alligator clip on this ground strap will permit quick connection to rig (and easy rig removal). Using an ohmmeter to check your installation, temporarily disconnect the groundstrap from the radio, and connect the ohmmeter between the end of the ground strap and the outer casing of the PL-259 antenna plug on the TX end of the antenna feedline. If the resistance is above .7 ohms, recheck/re-scrape all ground connection points until "poor connection point(s)" are found. THIS STEP ENSURES YOU RADIATE "A KILLER" SIGNAL!
NB: trunk lip mounting is NOT recommended for the OUTREACH 500.
It is recommended that you run your coax as far away from the ECM (engine Control Module) and existing vehicle electrical systems as possible and that you ground your tailpipe at the tip to help reduce spark plug noise, etc.
