Replace whip antennas

[Jaxryde]

Looking to replace my two long whip antennas for short runner ones. 2001 Ultra Classic with CB. Looking for direct replacement recommendations

[Ohio HD]

Look on the HD site, they sell the short antennas.

I have the two shorties from Kuryaken. Work just fine.

Ether way you go, once you install the CB antenna it's best to check the tuning since I've seen factory antennas way out of tune.  Also, going to a shorter antenna generally decreases your range due to the decrease in wavelength.  If you have a friend that's into Ham radio they might check the SWR for you (Those cheap $20 meters are no good).  You'd be looking to get as close to 1.1:1 SWR as you can get - 1.3:1 or lower is good.  The regular length (3') antenna I got from H-D was like 3:1 SWR with no real way to adjust it - look for an antenna that offers easy adjustment of the "loading".  Also, as you go smaller, it's harder to reach a low SWR.  Here's a picture of a small magnetic mount antenna being tuned - I could never get it any better than about 1.6:1 due to it's characteristics.

So where does one go to have their CB radio properly attenuated?

Ask around - most areas have Ham Radio clubs, and there are still a lot of people who have CB radios.  Maybe look for a store that sells radio equipment?  Google ham radio clubs?  or even radio repair shops?  The RigExpert AA-30 I have goes for about $220, which is why it's best to find a radio guy who will help you.  I'd help if you were local, but I don't think that's the case.

attenuated

attenuated

It's a term I learned from the guys in the radio shop who did all the two-way radio installs on our cars and motorcycles. I took it to mean that the radio and antenna were properly tuned and putting out a 5x5 signal in amplitude and modulation.

You need to find better teachers then.

Some good reading here.... https://books.google.com/books?id=wUzQN8GN_zYC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false

This was the Bible back in the day, and dispels some common myths.

The short whips from H-D are specific to either the CB or Radio, some of the others (like J&M) can be interchanged.  I have used both over the years and have not noticed any measurable difference.

Most likely because AM/FM radios can be run using a coat hanger for an antenna - don't try that with a CB.  I don't have a tour pack, but from what I've seen it looks to me like they put the loading coil for the CB inside the corner of the Tour Pack, which would mean they are base-loading the CB antenna, so unless the pictures in the GMA18 catalog are doctored, they use the same shorty mast for both the AM/FM and the CB, and make up for it with their loading scheme for the CB side. (Truth be told - top-loading is the best, followed by center-loading, with base-loading last.)  The Firestik2 I have on my SGS is a top-loaded, No Ground Plane (NGP) type.
