Using 1 antenna with 2 cards

the1andonly · 07-24-2002

I have a simple question, Is it posible to use one antenna with too cards? How will this effect the signal?

If your just going to flame to try to make your self feel superior please refrain from posting.

Thanks in advance

Remember the more connectors that you have spliced into your antenna feed the more loss you attribute.

Isn't it more than a question of loss?

I'd say loss would be your only issue when dealing with receivers but don't you have other problems when using two transmitters/receivers on a single antenna?

Wouldn't you need some active circuit to keep the transmitter A from overloading the receiver B?

As long as you are receiving only, no problrm, but you are going to have a 3db loss at best. As soon as you transmit, you are going to have a 3db loss in equipment. That is to say, you will probably blow the rx of the other card. Antennas are cheaper than cards, buy or build a second antenna.

il probably just go for another antenna.
