Does anyone know how the HI Z triangle array performs in an urban environment with minimum (50 feet) spacing? I would think nearby objects would affect the pattern/phasing although everyone's situation is different. I too am always looking to improve low band reception.
Read the documents on the HI Z website. My reading of them suggests that a typical urban environment will powerfully affect the way such an array will work. Arrays need, for example, to be a minimum of 200 ft. from a transmitting antenna and any metal objects near an array will affect its performance.
Just did that. I still wonder if anyone in an urban environment tried this with even a modicum of success.
