My tuner has inputs for two antennas. Is it OK to mount an omni-directional antenna above or below my directional antenna? Will they interfere with each other or somehow affect performance in a bad way?
Follow Ups:
Thanks for the replies. I will keep them separate. The omni I have used for years has two horizontal ovals in the shape of a cross. It's mounted in the attic and works fairly well. I recently bought an Antennacraft FM6 with the intent to roof mount it. Looks like I will leave the omni where it is for local and put the FM6 on the roof for distance.Another question: The FM6 will end up on the attached garage roof (single story) instead of the house roof (2 story) so it will actually be about 8 feet lower than the attic mount location. Is it correct to assume that giving up 8 feet of height is better than looking through the roof shingles, rafters, etc?
Depends on direction to transmit antennas. Do not want to *look* thru that entire 2nd story from garage location either, or look thru neighbors, trees, etc. Perhaps trial antenna location via mounting mast to plywood with sandbags for anchor ballast before putting permanent holes in roof proper; also allow shifting position along the roof.
Yes I thought of that. The good news is that for the spot I have in mind for the FM6, there are no distant station towers in the "shadow" of the house. There is a local station but the attic mounted omni will grab that one. Boston is to my east with no obstructions. That's where the FM6 will point. Thanks for the plywood sandbag idea. I will try that.
Space the two antennas apart by at least their element length to minimize interaction-interferance & it will be OK. If you have room for greater vertical spacing, all the better. An ARRL Antenna Manual from the 60's or 70's has a wealth of info applicable to any frequency. ARRL = Amatuer Radio Relay League.
the OMNI if its whip - to be an omni - has to be vertical, best place is at the top away from the also vertical mast. Try how close you can get before there is an audible degradation.If it is the type of exterior omni with a 'bent into a circle' quarter-wave dipole it should be as much as 10 feet away from the yagi as Ron says. start with 10 and approach 6 feet.
NB Avoiding lowering the Yagi is most important!
