Top Quality Materials

  • Black poly jacket “window design” 300 ohm balanced line twin lead. Sturdy 18 AWG, 19 strand copper-clad steel conductor. Power rated up to 70 watts; field tested and recommended at 50 watts max. Great for use with most portable and mobile radios.
  • 6 ft. 50 ohm RG-174/U coax – lightweight and flexible for ultimate portability!
  • True 50 ohm 3-piece crimp BNC connector – no compromises.

Careful Workmanship

  • I build each of these antennas personally and meticulously by hand. Each is made as if it was for my own use. I have over 20 years of soldering and electrical fabrication experience, and have made dozens of twin-lead antennas of this particular design.
  • Coax connections are wrapped, securely soldered and sealed. Coax is additionally reinforced to the twin-lead cable with a wire tie for additional mechanical strength. Exposed ends are also sealed for weather resistance. Connections and open ends are covered with heat shrink for durability.
  • A true 50 ohm 3-piece BNC connector is carefully installed with a ratchet crimp tool. Heat shrink is then applied to coax connection for stress relief and strength.

Inspected, Tested and Tuned

  • All materials are carefully inspected before use and handled with great care to avoid kinks, abrasion or other defects.
  • Assembled antennas are final inspected to ensure correct measurements, solid solder connections and sealed, durable construction.
  • Using a VSWR meter, each antenna is tested on the air with 5 watts input. Each is tuned for less than 1.5:1 SWR across the 2-meter Amateur band. They are broadband enough to acceptably cover the MARS/CAP bands as well!

Proven in the Field

This exact antenna design, materials list and assembly procedure has been field tested by Harford County ARES and RACES, and reported to provide excellent performance across the 2 meter Amateur band.

Useful and Practical Emergency Antenna

This antenna comes with 6 ft. of lightweight RG-174/U coax attached, with your choice of connector for use with many handheld radios.

The 2-meter roll-up J-pole is lightweight (approx. 3 ounces), compact and effective! The antenna can be set up quickly and easily by hanging out a window, attach to a ceiling, or toss a lead sinker over a tree branch with kite string and hoist it up. Slide it inside PVC pipe for rigid vertical installation (retuning required).
