Distance between discone and omniX in attic?

[ApexMark]

I currently have a Tram 1410 discone in my attic and am about to install an OmniX up there also. Is there a minimum distance I need to consider between them? I have plenty of room. I use the Discone for scanning only. It's all wood and shingles up there.

Thanks. I'm not very knowledgeable with these things. I'm using quad shielded rg6, run of about 30'ish feet down into my room.

Regards,
Mark

If you're using both antennas for receiving only, there is not likely to be any significant interaction between antennas.

There's no specific receive mode in antennas, they will interact just as much in receive as in transmit. Generally it's said to be 1 wavelenght where it will have absolutly no interaction, but that's usually not possible at lower frequencies. Any metal will act as a shield for radio waves so keep the discones bottom part away from the other antenna as much as possible to reduce the angle it covers that screens off the radio signal from that direction.

/Ubbe summed it up. At least one wave length at the lowest frequency.

OmniX is probably VHF, so two meters or about 7 feet.
