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
I'm surprised HF would be used - I've heard of old microwave links being
reconstituted, but HF is interesting. HF trading usually focuses on
getting to the computers in NY area. I suppose you could do that on a
skywave path "sometimes".
