Antenna dual 2m 70cm quagi

Hi, newly licenced here in the UK with only 10w to play with, I am looking to build a small high gain directional rooftop antenna for both 2m and 70cm as I live way out in the Northumberland countryside out of range of all the nearest repeaters with standard vertical antennas.
I was looking at the quagi design for my first home brew antenna project and wondered if a 2m and 70cm quagi could be combined on the same boom as it is driven by a basic quad loop and should not (from what I have read) be affected by other loops and elements on the same boom is this correct?

Hi Phil try a quad instead of a quagi. With the quagi, the directors are mixed together and interfere. With a quad, the 70 cm is inside the 2m quad and gives minimal interaction

Cheers for that Al, after looking again I had decided on a 4 ele quad for 2m only as the 70cm use around here is little to none so it would prob. be a waste of time and effort, great site by the way and thanks for posting all the required info.
