I would like to run multiple di poles for 11 meter use at my house. Can you run multiple antennas at one time or would that be am impedance problem. Any help would be great thank you

To run multiple antennas, you'd be co-phasing. You can find a nice write up at:

Well, they may not let me put in the link. Search for The Ultimate Guide to 11 Meter CB Antennas. There you'll see under performance tips, Co-Phasing.

73, the only impedance problem might be due to having several antenna too close together and one affecting the match of another. That would have to be pretty close however and if you can keep them at least 15-20 feet apart, part to part, then you should be OK. This spacing will not prevent interaction, but I doubt you will see any impedance affects that are measurable. Being this close together may however, skew the radiated patterns a bit.
