[TowerTalk] Two signals on the same frequency?

[Chet]

I don't think you will be any louder but At least one consequence of tx's on
the same freq is a much wider bandwidth.
"Hypothetically" It would likely  keep the other contesters from as cq'ing
close to your frequency as they could running a single xmtr.

Subject: [TowerTalk] Two signals on the same frequency?


A hypothetical question:

I have two antennas for the same band. The antennas might be same kind 
(eg. two dipoles, two yagis) or different (one dipole, one vertical).
I transmit with two separate transmitters - one to one antenna - but 
modulate the transmitters simultaneousl*y *with same key or microphone.

How does my signal-strength change on the other side in comparison if I 
used only one transmitter and one antenna? The antennas are not phased 
to each other and they might be quite apart from each other.

I know that the advanced contest stations have one beam to eg. JA and 
one to Europe etc.  But if they turned both antennas to JA, would the 
signal-strength go up?
