It just unscrews counter clockwise. If its tight you may be able to grab near the antenna mast base gently with a pair of pliers.

 

ok cool...thanks

 

not hi-jacking the thread here,but how does the shark antenna install ?

 

Unscrew the mast, connect the shark-fin pigtail to the base, carefully glue it over the antenna base (they usually use double sided tape).

 

Is it a good seal? Water can't get in between the gaps?

 

Mine seems like a good seal, haven't had any issue with it. Even if water did get in there is no place for it to go since the old base is still in place.

 

Thanks! One more thing to add to the mods list.

 

Can you link me to what's out there as a good replacement?

 

http://www.visualgarage.com/ The Mark II is for the 2011/2012/2013 Jeep Grand Cherokee. It's $81 including shipping charges.

 

shark fin looks so much better than the mast antenna.my only question is regarding the sirius antenna wiring.any problems getting it inside the shark fin? also,how's the sairius reception ?

 

The satellite and GPS antenna are in the base that the sharkfin covers. The sharkfin is mostly plastic and doesn't appear to shield or interfere, the fin itself contain only AM and FM antenna elements.

Looks are subjective, but I think the sharkfin is too big, like the mast better... but that's just me. I don't think the fin gets in the way of roof rack loads, however.

 

To me, the Visualgarage sharkfin looks odd the way it droops down toward the back of the unit. Hopefully the one that comes on the 2014 WK2 will look much better since I plan to get a new 2014 WK2.

 

Get an OEM SHARK fin

Don't waste your time with a clunky odd shaped cover up shark fin.

Buy a 2014 OEM shark fin 5091352AC, or get your dealer to get you the painted one TO MATCH your car color.

If your 2011-2013 wk2 only has AM/FM get a 5091902AA and the connectors are plug and play.

Most people on here will have navigation Sirrius and am/fm and need the 5091352AC.

This one uses a double blue fakra connector and is why all the noobs say it won't work.

There are no pre made fakra adapters for this application. So go on fleabay or Google and look up a double Fakra C male connector, and some rg179 coaxial.

The double c fakra male will plug into the double fakra c female that is on the new antenna. The green wire side of the double c fakra is the Sirrius/NAV signal. So this wire will need to have a single FAKRA K female (green) connector to plug into your wk2 fakra k male that is up in your roof.

The other side of the double fakra c connector will simply butt splice to the gray w/red tracer wire in your roof. This will supply power to the "amplified" antenna.
I suggest just cutting off the black power connector and the green fakra k female of your mast antenna if it's broken. If it's not broken and you want to sell it, try to find those exact connectors on flebay too.

The white fakra connector for am/fm is direct plug and play.

Enjoy!

 

Got my sharkfin not long after I got my Jeep in 2012. I haven't had any problems whatsoever with radio signals or Sirius. Also, since my Jeep is White Gold, not a color used today, the 2014 will not work for me. The company I purchased my sharkfin from painted it White Gold. Unfortunately I screwed up the paint job by trying to be 100% perfect since there was a little white spot where they obviously cut out the piece from the mold. Using touch up paint over areas, then another are, then another, it just got worse and worse the more I tried to hide my mistakes. It look like a mess from the side, but since I'm not over 6' tall I can't see the horrible mess I made.

 

The two part numbers I gave are both textured black and neutral to work with all color vehicles, like the original base/mast style.

I was just saying there are other part numbers if want the painted versions.

1yg06axrae For example is the brilliant black crystal. That's what I used on my 2011 overland.

 

This must be recent.

I checked with my dealership before purchasing the sharkfin.
Dealer said they could not fit 2014 on older models.

I like the look of the sharkfin.
Very satisfied.

 

So you believed what a bunch of low level paid guys who couldn't really care less about your desires to upgrade your older model said? These dudes stare at a computer screen looking at a bunch of half *** drawn black and white schematics and read 5 word descriptions of their parts.

Again, it's not a direct plug and play... so no, for the dumb, timid, retarded, scared it can't be done. If you have any skill or knowledge about coxial and simple wire connectors you can do a minor mod that takes less than hour and it will work.

I'll post photos of mine later tomorrow..

I have a 2011 overland. Mast got sheared off by garage door. I bought the new mast but couldn't get the sheared bolt out of the old base. I tried to use an easy out and it stripped the nut in the base so I had to remove base entirely. On a whim I tried the 2014 shark fin and quickly figured out how to change the connectors for it to work.
All is golden. Been riding solid for a couple weeks now.

 

I'm happy with the sharkfin.

I prolly should have done a bit more research.

The 8 minutes of effort I put in adding the sharkfin was reasonable.

Lesson learned I guess.

 

Removal of Base

Can anyone tell me how to remove the base? is it just double sided tape? my wife hit the garage door with it and it broke off the antenna and the base now wobbles and I do not know how to remove it nor can i find a video.

Thanks!

 

What year? Early models you had to pull down the headliner a bit and undo a clip or two.

 

It's a 2012 Grand Cherokee Limited.

 

The OEM antenna base snaps into the hole in the roof (it has two retaining tabs). Then its bolted from the inside (one bolt). The mast screws onto the base. If the base wobbles, you could get a water leak into the headliner there. If it wobbles you may have a broken clip. You can try pushing down on the base and see if it snaps into place. I don't think I've read of anyone here that busted the base, however. Plenty of masts have been destroyed, however.


Aftermarket Sharkfin antennas are double sided taped to the roof over the base.

 

Okay got some tape on it until the new parts come in!--couldnt snap it back in place. thank you for your help!
