I just installed a cx7 (also same part # for Speed3) antenna on my 3. It's not super short but it's significantly better than the stocker and there is no perceptible degradation of reception.

$13 - $17 depending on your dealership

Would you mind doing the signal strength check on the stubby vs. the stock antenna to see if there is a measurable change in reception? To do this, turn your radio on to AM or FM and then press the power button and "2" at the same time. You should get a number that fluctuates depending on the signal strength.

I'm thinking that AM radio would be more susceptible to lower reception so do you think you could do the test using AM? Thank you!

Sorry to jump in here but, I just ordered the CX-7 antenna from Tonkin and saw this post. I'm about 42 miles from Boston FM stations, 15 miles from Manchester FM stations and 4 miles from a Nashua FM station. Also, 42 miles from AM channel in Boston.and just did the test you described with my stock antenna.

Boston FM channels (all but 1) constantly fluctuate 5/6/7, the oddball out was 96.9 and it was a constant 3/4
Manchester FM channels constantly fluctuate 7/8
Nashua FM a steady 8
Boston AM a steady 1, no static


I'll have the CX-7 antenna on Saturday if it arrives on time. I'll update these numbers for comparison then.

Is that snow in Nova??!! if so where?! :shock:

Btw, this antenna is the best "looks" mod for the money. Really brings the car into the 21st century.
AND the signal doesn't degrade either!

moneypit, thank you for doing this! It'll be nice to have some actual hard numbers to see if there really is no signal degradation from going with a stubby. You say that you get no static on the Boston AM that has a 1 signal, does that mean the station still comes in completely clear, or you get no signal at all, not even static?

Looking forward to seeing the results of the comparison!

I'm off tomorrow so I will try to do the signal test with both. I live in the country and am 20 miles from the closest station.

As for the "snow", it's just play sand from the summer.

The AM station comes in crystal clear with a signal of 1. Passing under major powerlines (running up to Canada?) causes some distortion. but, this is only in that one location.

I was also able to check the following from Woburn Ma. today:

Boston FM channels from Woburn (about 10-12 miles) steady 8 on all.
Manchester FM channels (about 36-40 miles) constantly fluctuates 5/6
Nashua FM (about 32 miles) constantly fluctuates 4/5/6
Boston AM a steady 3

Lower the number, the better the reception?

The higher the better. Here are my results. I tested with the CX7 antenna first since it was on my car. After installing the 3 antenna and scanning AM, I did notice that the stock 3 antenna picked up a couple of stations the cx7 didnt lock in on.

Station CX7 3
89.9 5 6
92.5 4 5
103.5 1 1
1250 3 4
1420 3 4
1490 5 6

I'm surprised you got a 1 on 103.5 (WTOP?) they have 1 of the best signal around here.

Here's the update

...42 miles from AM channel in Boston and just re-did the test with the CX-7 antenna.

Boston FM channels (all but 1) constantly fluctuate 5/6 (was 5/6/7), 96.9 is 3 (was 3/4)
Manchester FM channels a steady 7 (was 7/8)
Nashua FM a steady 7 was 8
Boston AM 0 (was 1), clear audio.

I honestly can not tell the difference in the quality of reception. Looks good and works good, another great buy from Tonkin.
