Great product works as it should and does the trick for a bigger antenna

Pot bellied Spring

Thought it to be a bit much, but turns out to be perfect for my application thank you for the up grade and advise

Stronger than it looks

Have 102" whip on it and it holds up well even at highway speeds. Have mounted to the left quarter of Nissan Rogue with a scratch built aluminum bracket and has almost dead flat SWR.

Sturdy Spring

This is a great spring for the 102 inch whip antenna. I love the whole setup including this spring. Highly recommended!

Sweet little spring!

This is a great spring for larger antennas such as the 102” whip antenna. I have mine mounted to a Jeep Wrangler and this spring allows it to flex and not rip the mount off the jeep when it hits trees and canyon wall while offroading.
