David, Thanx for the drawings, they arrive by snail mail late last week. Once I saw the sketch with the diode across the switch what I needed to do was obvious(DUH). Short description: Power to switches center lead. Antenna power lead goes to the switch's 'down' connection, along with diode's cathode connection. Antenna sense lead goes to switch's 'up' connection along with diode's anode lead. When switch is in UP position, sense lead gets power from the switch contact, & antenna power lead is energized via diode. When switch is in the down connection, antenna power lead is energized by the contact, but the diode blocks power from flowing to the sense lead. Jonathan, HR-1 Should be fine. Most of the HARANDA varients are cosmetic: antenna lengths, black vs std chrome, mounting trim, etc. The HARANDA motors are pretty much the same. Also most Jap antennas use the HARANDA motors. Only thing I ever ran into was that my FOZDA ('91 Ford Probe built by MAZDA) had the up & down wiring colors reversed. It's actually less work to hook up a fully auto antenna setup to work like an semi-auto with the up/dwn switch than to rewire the auto antenna's relay for semi-auto operation. All it takes is 1 moderately high current Diode! | ||

One thing to watch for is different motor controls. The wiring diagram indicates that the stock antenna goes up with power applied one way, and goes down when power is reversed on the same leads. When no power is applied, it stays where it is. Many fully automatic antennas go up when power is recieved from the stereo, and automatically retract when the stereo power is removed. A separate power feed runs the antenna, with the stereo lead being only a signal. You may need to check the antenna you have for what signals cause the antenna to raise/lower. p.s.: In the wiring digram key, "BR" is translated as "white striped red", which I suppose could either mean "white-striped red", or "white, striped-red". Is "bianco rigato rosso" any less vague? (I need an Italian grammar guide.)  | ||

Pretty much any semi-automatic antenna will work; you just want to make sure it comes with a sufficient number of adapters (at least a couple) to fit the profile of the fender. Most come with four or five different adapters. | ||

At the risk of making this conversation even more confusing, does anyone know if the Harada MQ-1 will work in a 77 GTB? My antenna (which I doubt is original) is dead! | ||

OK, White, White w/Red probably matches my wiring. The white is just pretty aged so it looked tan in dim light. Looks like the switch end of the wiring has been re-routed over to the receiver then. I was hoping the wires from the switch were still intact & I just hadn't located them. Now I get to pull the console to hook up the switch again. | ||

Verell, Here is a photo of the antenna area from my car.  The wires appear to be both white with a red stripe (more white than red). There are only two wires. You should have a wiring diagram in your owners manual to check the colors for your car. Rob Baylor www.ultimatepedals.com | ||

I dunno for a QV, but according to the 328 wiring diagram, the antenna motor wires are both red with a white stripe. | ||

Rob, My car is an '82 308 GTS QV. I know the general area, just can't find 2-3 unattached wires! Perhaps they were disconn. at the switch & reused to tie the head unit to the automatic antenna? That's why I asked the color. The 2 wires used for the antenna are brown, and brown w/red stripe. Also I don't know whether the antenna uses 2 or 3 wires in semi-auto mode. | ||

Hi Verell, I'm not sure about your 328 but on my 85 308 the antenna wires end in the right hand side (RHS) of the trunk, behind the black trunk lining, directly behind the RHS rear tire (inside the trunk), and in the same general location as the RHS red rear parking light (say that 10 times fast).

Mike, My car came with a HARANDA M-4, but it was wired for auto operation with the JVC CD receiver. I just want to re-wire it to work with the antenna switch. BTW, I still haven't found out where the trunk ends of the wires from the antenna switch are. Anyone remember their colors & how many there are? | ||

Verrell, for your 308QV, the Harada MQ-1 is a drop-in replacement, all the same wire connections as my 308QV's Bosch unit. | ||

A while ago, the Whitney catalog had some semi-automatic antennae listed. I used one of theirs in another car and it worked well. | ||

Has anyone spent the time to figure out how to convert one of the japanese universal power antennas to semi-automatic operation? If so, please post or eMAIL me as I'll be installing one tomorrow & would like to at least restore semi-auto operation. After all, that switch is just sitting there being useless otherwise. | ||

Gianluca, The stock antenna for a 308 is semi-automatic in operation. That is it is actuated by a switch. Newer cars have fully automatic antennas that are activated electrically by the turning on the stereo itself. The switch is located on the console of a 308. Your antenna should have a chrome mast, chrome cover and black plastic/rubber or vinyl baseplate. I described the 328 antenna previously in this thread | ||

Thanks David and Mike. I'll see what I can find. Mine has a nice 30 degree bend in the top | ||

David, can you please explain the difference between the 308 and 328? I need an antenna too but the car came with a "whip" so I do not know what it looked like. Also, what is the difference between a semi-auto and fully-auto? Thanks, Gianluca | ||

Mike, the 308 versus 328 antennas are quite different in appearance. | ||

I don't see the semi-automatic antennas listed anymore, you will need to email them for details... | ||

Tillman, That was me. The stock Bosch antenna is no longer made. As you recall it had a black cap and tip, with a chrome mast. Most replacement semi-automatic antennas are chrome, completely. I found a website where they sell a black chrome attenna, black mast, cap and tip. Unfortunately when I ordered, they were out of the black ones, but had chrome and the black spare parts. So I ordered a chrome semi-automatic antenna, and replacement black mast and replacement black cap kit. Total cost was may be $70 or so. www.antennaworld.com Difficult site to surf. If you get stuck, email them or call them. I found them very helpful, when I explained what I wanted. If anyone needs a totally chrome Bosch antenna (fully automatic, but can be converted to semi-automatic operation; will include instructions). Email me. I paid $135 for it, but would sell it NIB for $100 including shipping to you. | ||

It's not black, but the Harada MQ-1 is a perfect replacement for the original Bosch unit. | ||

I don't think any 60,000 mile 328 will win a concours, so I might as well tweak it a bit It's a shame I don't have $7000 to blow on carbon fiber bits... | ||

Someone mentioned a while back a black replacement antenna for the 328. I did search the archives and couldn't find it. Does anyone have a part number/brand/etc? |
