Howdy, TowerTalkians -

    This is a little off topic so feel free to use your delete key.     In the last month I've spotted 3 big HF yagi installations mounted on non-ham towers on non-ham properties. One had 3 big yagis, one was a big SteppIR by itself and the other had 2 big SteppIRs. All were pointed fixed east (I'm in the Seattle area).     Turns out that these are probably used in High Frequency Trading. That is, stock trading where fiber wasn't fast enough and the users have turned to HF to decrease the lag time. I thought it was pretty interesting and I'm curious how much this is being used. And at least they're not in the ham bands - hi.  Cheers,Steve    K7LXC
