Hi
Can I use more than one antenna to my transmitter system (max pro 3 and 40w amp)

Whats best solution to get better range? I use a High-Gain Vertical Half Wave antenna now with this spec:

4.2dB gain over a dipole aerial!
Narrow and Low radiation angle!
SWR better than 1.5:1
Reduces risk of TVI!
4 MHz RF Bandwidth

In your case sensible thing to do would be either to mount
antenna higher or use more power (~150W for 2x more range).

The other way would be to use multi-bay antenna but that'd
be quite an investment as you'd need 6-8 to make a big
improvement.

Marko is right, and in case you were wondering, I looked this up once and, while it can be done, there's a lot of math

Here's the info:

If I change antenna? Can I get more range?
Is a tuned dipole better than vertical half wave antenna?

I have 40 Watt now, and thats max for what I can use.

You can't get more omnidirectional range with a single antenna of any kind.

You could get more range by using really lots of dipoles, as I originally
suggested.

The more the better

Okei, thanks for answers

Maybe I can put up my old transmitter another place and let it recive signal from the new transmitter

Sure, but it will have to be on another frequency, if the
signals overlap.

Yep

And to all readers of the forum; you can tune in RadioLive on internet if you want to listen to us

I put this here:

I look at my SWR meter today, and I wonder, how many watts output I have? I dont think I can read the swr meter correctly

Looks like a cheap CB wattmeter, its hard to say whether reading is correct.
Also, note that with a swr significantly from 1:1 the power reading becomes
less and less accurate.

How can i get lower SWR?

Change frequency?

The antenne is tuned to 100.8MHz but the bandwidth is plus/minus 2 MHz from the centre frequency, and i transmit @ 99.6MHz

Tune antenna to 100.8

Depending on the quality of swr meter its reading could be off as well.
