Is there an aftermarket sharkfin antenna that will do HD/Radio, GPS, and etc;, on an aftermarket antenna? I don't care if I have to run new wiring. I understand that for Satellite Radio, the extra module you purchase probably comes with an antenna of it's own.

Our cars don't like shark fin, I've tried a few, including OEM MK5/6, made my own adapters, reception isn't the greatest. Let me know how that booster works out.-I respectfully disagree. I bought an aftermarket shark fin for my MK4 wagon and it works fine. Though FM is ALL TALK/commercials now days, I mostly use Pandora.

Well, my factory antenna is garbage. I can barely get a signal on stations that I get fine 100 miles away in other cars that I have owned.

I went with an OEM for my wagon. This thread covers the various VW antennae

it's probably got the typical corrosion that happens to it. I replaced my with a new one and radio reception went back to perfect.

If I am going to replace it, I'd rather do it with a low profile one. Not the factory one that looks like it was made for an older cell phone setup.

Complain about crap reception, then express desire to install smaller antenna for aesthetics. No cheating physics - antenna needs to be a minimum length to catch the wave length of the radio signal, reliably enough for good audio.

That is why I just put a vinyl cap on the mast stud since I don't listen to AM/FM radio anymore. However, I do carry masts in the back "just in case".

I've had low profile antennae in other cars that caught signals 100+ miles away. The factory antenna cannot even catch a signal that is 25 to 30 miles away.

It depends on where an RF amplifier is located. VW seems to have placed it in an antenna base with a short mast where it is subject to corrosion; other systems use an amplifier circuit in the radio receiver itself and just rely on a plain 1/4th wavelength mast antenna. BTW, when the amp is in the antenna base, it needs to be powered; if the power supplied by the receiver is interrupted, no amplification.


Edit. The old standard whip car antenna was about 2.5 feet or 30 inches long. This is roughly the length for the middle of the US FM band (98 MHz) which has a wavelength of 10 feet (120 inches). Dividing the former into the latter tells us the whip mast is 1/4 of the FM band center wavelength. In metric terms they are 76cm and 300cm lengths respectively. The kicker is for the AM band the center wavelength is approximately 100 times longer! Thus the whip is only about 1/368 wavelength for the AM band.

My understanding is VW also uses an antenna whip with a resistor pellet and tuned wire loop wrapped around the whip.

I have a Jetta MK5 antenna base (5N0035501B) on my Jetta MK4 and it works great for everything my head unit supports: AM/FM, SiriusXM and GPS. I don't use the 4th "GSM" wire. With that said, I don't have a stock head unit. I have an Alpine CarPlay head unit and I ran individual wires from it to the antenna base for SiriusXM and GPS. I got the individual long antenna wires from ECS and they were plug and play with my Alpine, no adapters necessary. And, my AM/FM reception is good even with a stubby Sharan-style billet antenna from cravenspeed.com made locally in Portland, Oregon Our TV and radio towers here in town are way up high in the west hills, so that may help as well with reception. However, I didn't notice any difference when I was using the OEM antenna either.

Do you have a link to the ECS wiring?

Looks like the antenna I used several years ago except it is AM/FM/Sat radio. The original P/N 1K0 035 501 C is discontinued, replaced by 5N0 035 501 A.


Your Jetta is a sedan, correct? Then you don't have the problem of the rear hatch of the wagon hitting the mast as I did.

If that doesn't pan out, here is a list of VW part numbers for various lengths of FAKRA to FAKRA cables and adapters. For my Jetta Wagon, I ordered the 700 cm FAKRA/FAKRA cable and the FAKRA (M) to SMB cable.
