Re: [Repeater-Builder] Combination of Omni and Yagi antenna
I can supply .pdf files of power divider construction (from both ARRL RSGB). These are how I built mine; they work. Maybe post in the files section? If so, who do I send them to?

Decibel Products called something similar a Keyhole Pattern array. (3 dB omni and 2, 3 ele yagis in VHF).
