Spotlight: W4ISA Makes DX Easy!


  • 20' Vertical Dipole
  • Tuner in the shack
  • Lightning, Surge Protection
At Greyline Performance, we strive to deliver exceptional HF antennas that elevate your ham radio experience and look good too. We're honored to share a fantastic testimonial from Peter Dehman, W4ISA, who exemplifies the joy of connecting with the world using our 20' Vertical Dipole Antenna. He writes:


Good afternoon,
Very pleased with the 20' antenna. OUTSTANDING fit and finish of the highest quality!!! Went together like a charm. Absolutely NO issues. EXCELLENT instructions!
My tuner is in the shack and the antenna performs very, very well with buried LMR400. OPEC LP-350A Coaxial Lightning Surge Protector is in the waterproof box pictured along with the 3D printed holder for the Ladder Line/PL-259.
NOTE:  It is best to unplug ALL electrical connections from the wall and coax connections to the radios, etc and ground them when you are not on the air!!!!
GREAT results working everything that I hear!!! 10 STARS ++!!!!!

"Outstanding fit and finish... EXCELLENT instructions! Went together like a charm!"

Peter highlights the quality and ease of use that are hallmarks of Greyline antennas. Our meticulous design and manufacturing ensure a smooth assembly process, getting you on the air quickly.

"Absolutely NO issues...performs very, very well..."

This is the heart of what Greyline Performance is all about. We create reliable, high-performing antennas that let you focus on making contacts, not troubleshooting equipment.

Tip: See our Assembly Documents pages provide valuable resources for new hams who might be unfamiliar with antenna assembly. Pretty simple, right?

"Tuner in the shack...buried LMR400..."

The 20' Vertical Dipole Antenna is designed to work seamlessly with a variety of setups. Whether you prefer a tuner in the shack or a remote tuner at the antenna, this antenna delivers excellent results in both scenarios.

"10 STARS ++!!!!!"

Peter's enthusiasm speaks volumes about the impact the 20' Vertical Dipole Antenna has had on his ham radio adventures. We're thrilled to be a part of his DX achievements!
