The one without the tunable tip is better for a standard 40 channel radio. Not a big deal, just a small percentage you can/could add to the whole.

I use Firesticks. Never had to trim and always under 2 on my meter. Might just be the stick itself. Why change the factory antennas if they are working and low reading on meter?

Antennas can still be off but have a good swr..
Had good swr with an antenna behind the cab but i was lucky to get 10 mi..Resonance and reflect and resistances were all off..
So many out there (as i have said a billion n one times now)still think swr is a good or bad performance marker..Its not......To many exames of what swr really does and doesnt me out there,been proved a million and 8 times..
There i go beatin a dead horse again..O well i can see the replys now.. -

Its possible..I had an issue with a 7ft skip shooter..Tuned fine in the yard then right at 57 it would shoot my swr up and my radios swr protect would kick in and shut me down..Took me a few to figure it out but sitting still onthe analyzer it was fine but when i used a bungie cord to pull it back FOUND IT...Brought it back and shop tested it and it was at the base of ant..
So yeah its possible seeing it was a 3plus on all 40..
If you have the room height wise,go taller till your close to 13'6" ..Slowmover1 and _33 Thank this. -
I agree. All I said was that everything else being equal, which would include the ground plane and the relative mounting positions etc, it's the length of a resonant antenna that generally determines its performance vs other antennas.
Slowmover1 Thanks this. -
Now i wouldnt put a 5 ft on a low mount point but i would put a 6ft on a high mount point and you will get a difference in performance.....Now if a 7ft goes on a low mount point and a 5 on a high the oerformance will be about the same when all else is equaled..
The windings are of same length in a 5ft vs say a 6 or 7ft just that its apreaded a lil more on a taller ant..
I played around with my 7ft skip shooter and a predator 10k with a long shaft(forgot its length 28" i think)and got slightly better results with akip shooter..Im not sayin the ss is a better ant but in the case of a low mount point it is....The 10k has a broader freq range than my ss..
I got a few vids on youtube..Did one today showing my results while sitting in the trk stop parkin lot in kenly nc..
I go by same name as here..Lol finally learned not long ago how to do this youtube vid thing.. -
Better off with tuneable tip style.. -
