RETRO-MOD: replace standard antenna mast with wind noise reducing mast

[RetroC10Sport]

This is how to replace your standard older antenna mast with a wind noise reducing, anti-vibrating antenna mast. This is for later model squares with fender mounted antenna. I noticed a lot less wind whistle when installed on my Blazer.

Difficulty level: 1/10 (1 being easiest)

What you will need:

~Antenna mast with the spiral winding from a 1995+ GM with a standard mounted antenna. Mine came from a 1996 Blazer.
~8MM wrench
~10MM wrench

First you will need to go to the junkyard and find the antenna mast. Difference is below.

You can find them on many GM trucks from 1995 on.

Take your 8MM wrench and slip it on to the flats on the base of the mast like so:

It just unscrews from the base.

Now take your 10MM and remove the original mast from your car or truck:

I used a flare nut wrench because they can be tight.

Installation is reverse of removal for the new mast.

Enjoy less wind noise.

Did this mod back in about '04/'05, including the rectangular base......all new from the dealer. Worth spending some $$ on. Now if there was a glue-in windshield option that did away with that fat, wind noise generating gasket.
