:D :D Please Post picture of “tin hat” mod so we can copy it…. :D :D

Seem to recall that the ref radiation is also emanating from not only the antenna but also from the transmitter itself and the coaxial lead as well……. 🤔

My in-laws too. But seriously folks, the people who design the radios and feedlines hold the radiation from the set and the feedlines as low as possible. Such stray radiation is considered a loss from the intentional radiation at the antenna.

We bought this more compact 4' antenna 14+ years earlier to replace the 8' unit. It has silver plated element that will last longer. Very long range and great sound quality. Worked much better than the cheap 8' unit that came with our boat. https://shakespeare-ce.com/marine/produ ... f-antenna/

Used a ratchet rail mount on right rear corner rail which allows for folding during transport and setup. https://shakespeare-ce.com/marine/produ ... ail-mount/

Would buy again.
