Hi Mike,
Thanks for your reply.
Yes, in Multi-Two stations you have 2 Running stations but you can install
few Multipliers stations only to work Multipliers...sometimes you find
Multipliers in one of the bands you have a Running station.

Subject: Re: [CQ-Contest] Multiband Antenna separation for Multiplier
station...
There is no simple answer to this question. How much power. Where are
the antennas pointing, etc.
You are asking for trouble being on the same band. You should have
lockouts to make sure you both cannot be transmitting on the same band at
the same time. I would also want to take the other radio receive to
ground while the other radio was transmitting. You should have bandpass
filters on both all radios in the contest station. That will help
everyone.
The lower the freq the more separation you will need. I don't know that
you can really get enough separation to guarantee a damage free operation.
CQ WW requires:
*1. Station location:* The area in which all the transmitters, receivers
and antennas are located. All transmitters and receivers must be within a
single 500-meter diameter circle. Antennas must be physically connected by
RF transmission lines to the transmitters and receivers.
So 500M is my answer :).
I have no idea why you would want to use your 2nd transmitter on the same
band as the 1st.
*2. Two Transmitters (MULTI-TWO):* A maximum of two transmitted signals on
two different bands may be used at any time. The log must indicate which
transmitter made each QSO. Each transmitter may make a maximum of 8 band
changes in any clock hour (00 through 59 minutes). Total output power must
not exceed *1500 watts* on any band at any time.
Hi,
We are planning M2 operation for CQWW SSB contest.
We would like install a Multiband antenna for the Multiplier station...to
avoid
damage receivers front end, what is the minimum separation between Main
antennas and a Multiband Mult antenna???
The worse case is trying work a NEW MULT in the same band we are RUNNING.
Any idea?
Thanks,
