VHF Public Safety, MURS, Marine, & Scanner Slim Jim Antenna


Our extremely popular Slim Jim Antenna is now available for the VHF 150 – 160 MHz band. This means our Slim Jm is optimized for VHF Public Safety, MURS, Marine band, and Business frequencies. The Slim Jim is an end fed folded dipole antenna that gives you approximately 5.5db of gain.  Plus the antenna also have the great low noise floor and wide bandwidth typical of our other antennas.

The difference between a J-Pole and a Slim Jim is simple: while both share the same design, the Slim Jim folds another 1/2 wave element over onto itself, turning the single half wave concept of the J-Pole into a double half wave, or ed fed folded dipole antenna. The folded dipole nature of the Slim Jim gives you about 2.5db of extra gain when compared to the standard J-Pole.


  • Increased gain: compared to a standard J-Pole the Slim Jim has about 5.5db of gain
  • Wider Bandwidth: Almost 8MHz of 2:1 bandwidth (double that of the J-Pole antenna)
  • More RF energy aimed at the horizon: with a take-off angle of about 7 degrees for the Slim Jim, compared to 20 degrees for the J-Pole
  • Compact size: the VHF land-mobile Slim Jim is still only 56 inches tall
  • Hear weaker stations: lower noise floor than a wire antenna will help you hear more and capture distant signals better.


  • 56 inches tall, end-fed folded dipole design
  • Gain: 5.5 db, 7 degree takeoff angle
  • Bandwidth: 7+ Mhz
  • Pretuned to 154 MHz: Just connect the coax and transmit
  • Heavy duty construction out of 1/2 inch copper tubing

Special tuning to your particular VHF frequency between 150-160MHz is available for no extra charge. Just leave a note during the checkout process of your frequency of choice and we will take care of the rest.
