Probably pruning for what sells the most - still a lot of choices. Although my 4E no sweeps is a great antenna, and I like it better than the DB36. Ask if you want one not listed.

When I looked last Friday you could no longer buy the standard 20-6M products ( 3E, 2E etc) . You now had no choice but to but buy an antenna With the 30/40M sweeps which have been problematic.

Go here
https://consumer.steppir.com/product-category/horizontal-antennas/

Tthen click on "3Element Products" ..You will see they no longer offer the 20-6 3E or under 2element products they no longer offer the 2E

What evidence do you have for that statement?
The web site looks like it has the same products they have for years.

Probably one of few things that is keeping S-IR alive ... I know they have REDUCED their product offering to hams in last month or two

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
