First may I say, happy Labor day. I have a 17-in shaft Predator antenna and I would like to know if I could add on a 9 inch Predator shaft to make it a little longer, for possibly better performance. Thank you.

Can you extend a predator antenna by adding another shaft?

You can, just be certain it will still be mechanically sound at highway speeds. You will need to retune the longer antenna as your lowest SWR frequency will move downward a bit from where it was after whatever tuning has been done previously.
Not sure what you're looking for in "increased performance", you may or may not see much difference depending on your situation.

So you want to put a 9" shaft on a 17" shaft? Why not just buy a 27" replacement shaft? Also there will be no difference between the two, depending on location.
Unless you trying to get it above the cab I don't think it will make a big difference.
And yes, it might be cheaper to call Cale and see what he wants for a real 27 inch shaft.
That's the really good thing about these antennas, you can take them apart easily.

I have the 27" shaft to raise the coil above the roof on my truck.
I have it mounted on the top of a Jeep. I do have the 27-in shaft but it's a couple inches too long around here so I have a 17 inch and a 9 in which is 2 inches shorter but makes a difference driving around and I was just thinking of it because I always hear longer shaft is better.
How would you connect them together? 3/8"-24 NF threads on one end and 1/2"-20 NF threads on the other.
Remove the 3/8"-24 machine screw on the end, use a 3/8"-24 plug tap and tap the hole deeper and then cut the shaft to the required length and install the 3/8" machine screw with Loctite.
Improvise, adapt and overcome!
Good Luck!

I would just run the 17 if that's what you got.
You are already above everything on the jeep and it's not going to make a mountain of difference.
Plus you have to worry about beating up the antenna with brush off road depending where you are wheeling.
