Finally got a "snip"

no not that kinda snip,,, trimmed the antenna about 4 inches with the trusty ole dremel... no more scratching the garage door

that's one way to do it.

does it still work,....you could have always just duct taped it to the pillar.lol

I swapped mine with the antenna on my wife's Pontiac Solstice. Two inches shorter made all the difference. Only problem is the mount. the H3 expects a male connection on the antenna, not female like the rest of GM. I actually had a few adapters laying around to circumvent this.

I found a short rubber antenna at Pep Boys to put on the Solstice later.

I do not care for the long thin stack antennas.  For the life of me, I can't figure out why any vehicle would still come with those.
I ordered a AMI 21" stubby antenna from hummerpartsclub. It comes with the exact adapter you need for the H3.
It comes in even shorter lengths, but I thought anything too short would look kind of silly. 
Here's a link for anyone interested.

EDIT: That link is to the black stubbies, but they have numerous other options here: http://hummerpartsclub.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=H&Category_Code=AMI_H3
 
I think I'm actually going to order one with the lasered black flames and I'll put the black one I have now on wifey's Tahoe.

Yea, that lasar one is kinda cool

Antenna length is paramount to good reception.  Do you notice any loss?
 
P.S. I have a standard 9' Door and my antenna doesn't rub.  Did you guys lift your H3?

Mr. Vader is right....The antenna it "tuned" to the radio and that's why it looks the way it does.  When you buy a stubby, the entire length of the optimal antenna is wound into the new stubby thus making the overall antenna shorter but still containing the same amount of wire for proper reception.  You should notice a decrease in reception now that you've done your dremel deed, if not in strong local stations then in marginal ones.  Length DOES matter!

To those of us not on the dark side...standard doors are only 7' tall.  I guess too much time in the Mos Eisley Cantina stunts our growth so we get smaller doors?

no difference in reception, and I live close to the mountain (on the "dark" side) so the radio clears up at exactly the point it did before the snip

Garage doors are referenced by width.  So it's a 9'x 7'.  Like a 2"x 4" isn't referenced as a 4"x 2".  So know you can enlighten me on Mos Eisley Cantina?

Dremel would have been easier but I took a hacksaw to my antenna and cut it exactly in half.  You guys are right about the potential loss of reception because the antenna is tuned to FM frequencies.
 
I'll explain why I cut mine in half (and not another arbitrary length).  Here's a very oversimplified explanation:
 
The average wavelength of the FM broadcast band is 3 meters (about 10 feet).  FM antennas have either straight or 'wrapped' wires that are fractional to this wavelength.  That is, there are full wave antennas (approx 10 feet of wire), three quarter wave, half wave, quarter wave, eighth wave...  you get the idea.
 
There is not a big penalty if you choose to cut your antenna at an arbitrary length.  (This is because 1 antenna covers a fairly broad range of FM wavelengths, or frequencies.)  However, try to stay at 1/2 fraction of the original length.  I have not experienced any noticable loss in strength, even on fringe stations.
 
BTW- AM radio waves are approximately 1000 feet and cellphone wavelength frequencies are about 3 inches.

I have a short "Cat Wisker" on my AM Crystal Radio.
Anyone ever try it?
