body and interior antenna removal help

[rdeeble]

hello faq

 

trying to remove this antenna from my parts car for my new drive i think its a Hirschmann but not sure.  For the life of me I can not  figure out how this base comes off.  It appears there may be two screws in the two circle openings of this base but i can not see them and so far a philips head does not seem to catch anything.  

 

Any advice?

May be slot heads or rivets.

 

My advice is buy a new Hirschmann on ebay.

All the Blaupunkt and HIrschmann antennas I've seen had small philips head screws down in those wells.  If your phillips scfrewdriver won't grab the screw heads, try carefully drilling out the heads, the remove the plastic base and cable.  Once they're out you can use a pair of visegrips to remove the remains of the screws.  When you get new screws, get stainless steel ones.

Yup, pretty sure there are screws there. I remember screws when I replaced my antenna.

yep thats what i did.  carefully drilled them out (and yes they were philips #1 screws but completely rusted through and through.  

I NOW have a new problem...

 

The new car (with freshly restored paint) has a much bigger hole in the pillar and no small screw holes. I REALLY DO NOT WANT TO TRY DRILLING MORE HOLES IN A FRESHLY PAINTED CAR (thats my inner anxiety yelling).  Any advice on how to attach this antenna? I have a really good fastener store nearby if anyone can think there some kind of fastener i can utilize?   Or is this set up for a completely different antenna that I should find ?

3M trim tape? I would just drill the holes but seal the back with seam sealer or RTV so that water doesn't creep in behind.

just a hack thought...

 

If the diameter of the base is wider than the hole... could you put a straight (longer) piece of metal behind the opening on A-pillar, with 2 holes drilled in it and simply tighten the antenna to that piece. Maybe 3m'ing the metal piece inside the a-pillar? I think you'd also need a rubber gasket behind the antenna.

 

/hack thought

 

edit: this is assuming the 2 screw holes fit in to the current larger hole on a-pillar.

yep i think the base will cover the hole - but screw holes out side of the main hole would be to close to the edge and not secure.  I was thinking too about a piece of metal behind - maybe loctite a nut on the other side of the metal piece and use machine screws to secure the base - a gasket is not a bad idea either...

the reason i didn't say bolt + nut was in case you want to remove it in future, without opening a-pillar fabric.

 

good luck

So project complete.  I had spazzed out some on the worries about the size of the hole it was not as bad as I had thought.  There was indeed enough room to drill.

 

For anyone reading this in the future here are a few tips.  

 

1. Get the right tool!  The two philips screws in the base require a "very narrow philips" with #1 head.

 

2. To fish your cable in use an old cable with a straight end and duck tape the end of it to the tip of your actual cable pin.  That way you can grab it through the cable hole in the body (right next to the hood lever) with some needle nose pliers to strong arm it through the hole - it will damage the cable but its the extra old one - then once through the hole you can pull on it to bring the new cable in.

this was very helpful" http://www.bmw2002faq.com/topic/77713-antenna-replacement/

 

3. Replace the base with stainless steel screws - the old ones i took out were pure rust despite a well preserved car.

 

4. Given the rust of those screws I choose to make a rubber gasket. I used a 1/8 thick rubber washer at Lowes and cut it to size.  This way as I tightened the base down it squeezed down on the rubber making a seal.

 

And yes I ended up making two very miner scratches to the new paint - but oh well - at least the first scratch was my own.
