Topband: BOGs in alley under powerlines

[HankP]

Is there any point in trying a 160 foot or so BOG down an alley if there are powerlines and phone lines and cable TV 15 to 30 feet above ??? (Along with Centurylink VDSL2 carriers across band 2 to 3 dB above my -100 dBm invvee noise. - at least they are not -75 dBm anymore after two days and two people and 75 days of hassle ) 

Probably not but maybe I am missing something - alley runs east - west . 

Anybody ever tried this ?
