Short Wave Listener Long Wire Antenna, 100KHz-30 MHz includes matcher, wire, insulators
Model # PA-SWL-1 includes MLB-2 Long Wire antenna matcher, 50 feet of insulated
wire and 25 feet of support cord and a end insulator for the antenna.
Great for short wave listening and works as a bent antenna, sloper,
inverted “L” antenna (Vertical and horizontal) or as a straight vertical
antenna. For best results use a counterpoise for the lower
Palomar Engineers Magnetic Longwire Balun has been redesigned for shortwave listeners and others needing to match a long wire antenna to 50/75 ohm coax feed line cable.
Specifications: Frequency: 100 KHz – 30 MHz. Input: 50/75 ohms for coaxial cable. Output: High impedance. Connector: SO-239 (for cable) wingnut/solder lug for wire lead (for antenna). Mounting: Stainless steel eyebolt. Size: 2.5” diameter. Case: White PVC sealed weatherproof. External ground bolt with wing nut for external counterpoise or separate ground.
The long wire antenna often has a high impedance in the 500-1000 ohm range and the MLB-2 transforms this high impedance close to 50/75 ohms efficiently coupling the received signal to the receiver. A long wire antenna with a matching unit such as the MLB-2 often has a 12 db (2 “S” units) better signal than a long wire without a matching unit.
