Portable Antenna

The KULDUCKIE (KD) is recognized around the world as the ultimate in a high performance portable antenna! Each antenna is constructed of superior conductive materials and hand tuned to the exact frequency specified by the customer. The match to the portable is assured by tuning the antenna on a 50 ohm "bridge" rather than a ground plane. This method assures the closest match to the portable where no ground plane is available.
KDs feature a rugged coating of polyolefin and PVC to assure superior performance under the most demanding conditions.
"Hand Built" High Performance KDs deliver greater transmit range and long life due to these unique features:

• Copper/brass radiators
• Exclusive "EXACTune" process individually scope tunes each antenna to exact frequency specified
• 2 to 1 or less VSWR
• Fully Soldered (not crimped) construction
• Fully sealed-Plastisol coated
• Injection molded housings
• Silver plated contact pins
• Larsen designed "super BNC" uses teflon insulator, silver plated pin and double spring design to prevent connector failure

• Attractive & durable PVC Finish
• Brass wound cable radiator for conductivity, flexibility and strength
• Fully soldered, not just crimped, for best electrical performance & long life
• Silver plated contact pin or durable brass connection provides excellent electrical contact and long life
• Available for UHF/800/900
• Approx. length: 6"

• Attractive & Durable PVC Finish
• Special low loss heat-shrinkable poly olefin tubing separates radiating element from outer PVC coating to minimize dielectric losses
• Highly efficient .50 steel & copper-plated radiating element means improved conductivity and performance
• Soldered electrical connection is covered with a copper jacket then flooded with solder to give double protection at the point of maximum stress
• Silver plated contact pin or durable brass connection provides excellent electrical contact and long life
• Available for VHF/UHF
• Approx. length: VHF - 8" UHF - 3"
