Co-phased?
Anyone run a base with 2 antennas working simultaneously? I never thought of it before and was just curious.
Wondering, could you run an omni with a beam and TX / RX on them both at the same time?
What do you think about that, huh?
Thanks.

Do-able, but probably not worth it. Co- phased omni's would get you some gain but become directional. The mis-matched antenna thing might be interesting, but I wouldn't co-phase them just on virtue of being mis-matched. Get a 50 ohm splitter (not a tee connector), but a true 50 ohm splitter if you wish to try it. They're not cheap... $50 maybe?

You could co-phase two omni-directional antennas...but then they wouldn't really be omni-directional. They would become bi-directional, favoring two directions over all directions.
Also, using an omni-directional and a beam at the same time kind of defeats the purpose. I guess I see where you're going with this...it would allow you to point the beam at someone so you were able to transmit and receive a good strong signal while still transmitting and receiving other directions. However, if not done right, it would probably be worse than just having one or the other. If the signals are 180 degrees out of phase, they'll cancel each other out.

Running both of the antennas from the same radio, as in co-phasing?Trouble wrote:Anyone run a base with 2 antennas working simultaneously? I never thought of it before and was just curious.

Or, running each antenna on a separate radio?
I am not sure which one your talking about.
If your talking about cophasing... [Please login or register to view this link]
But if your talking about each antenna on its own radio, then you had better have a big property to separate them because when you transmit on one, then receive from another you will have de-sentitization (desense) big time.

ive never seen anybody co-phase a base antenna yet but, i do run two diffrent base antenna outside of my house, one for my radio, the other for my wife's radio, but like already said, if ya do it, it will become one direction like north/south or east/west, i think a set of beams would be easier to use instead of co phasing 2 base antennas...Dj

2 50 foot towers
both with Laser 400
both with rotors
hooked to 1 rotor box both beams point north when you hit the brake and left both beams go left when you brake then click right both beams go right
outstanding sight to behold
oh and about 12 Kw on standby
