Stacking width for 2 x 9 element yagis at 477mhz

[motu1981]

Anyone know the exact width to stAck 2 x 9 element UHF yagis with a power divider?

477mhz
2 x RFI 9 element Yagis
Power divider with two ports tuned at 477
Vertical polarising

What is the width between each beam?

63cm?
31.5cm?
1m?

Thanks

I believe for 6 elements at UHF it's approximately 100cm, RFI should have this information somewhere, I'll see if I can dig it up.

From ZCG:

"The separation distance will vary according to the number of elements and changes from approximately 1.3 wavelengths for 6 element models up to 2 wavelengths for 15 element Yagi’s"

Thanks Guys

1 wavelength at 477Mhz = 63cm

1.5 wavelengths = 94cm

2 wavelengths = 1.26m

RFI chart is somewhere around 1.5

just want to know if there is any difference in distance between phasing with a harness or using a power divider
