So I got an older diamond CP22E for my FT2900R but I get around a 1.2:1 at 136mhz and 2:1 at 144mhz. Do I need to tune the SWR down on the 144 which is where I do most of my operating? Thanks in advance.
It is too long. You meed to shortened it.

The antenna is to long,need to shorten it up a bit,with VHF it doesnt take much cutting on an antenna to make a huge difference .
And yes SWR can make a difference .When a signal is reflected back into a radio ,the radio gets rid of the reflected signal in the form of heat ,as you know heat is a radios enemy .If the SWR is high enough it can simply cause parts to fail when you key the mic..
.It would be well worth the time to tune the antenna for where you plan on operating at.Your radio will thank you in the long run
Thank you for the reply. It's much appreciated. Should I be cutting in half inch increments?
If it was me, 1/4 " increments.

Thanks for the replies folks. Very much appreciated.
One more question though, if I manage to get a better ratio than the one I have now, will it affect RX?

Almost certainly not.
very little if any
