More than one antenna?
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.

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.
These antennas would work better, too:

Of course you need at least 3 of these, better yet 4, to get circular coverage and gain.

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

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.

Tune antenna to 100.8
Depending on the quality of swr meter its reading could be off as well.
