Pacific Antenna has a 41db in 1 db steps kit
Hi Dean,
I think it's fine for HF use, they claim up to 200MHz, but I'd suggest 30MHz is more reasonable before the performance tails off.
Ideally, it needs to be in a metal box, otherwise you will get signals leaking in (and out), and I suspect it wouldn't achieve 40dB isolation whilst in a plastic case.
You can obtain push button binary value step attenuators, in various power ratings and step sizes, rated up to a few GHz from AliExpress, with prices starting at around $25 USD for a 2w 0-30dB version.
Search for "0-90db/60/30 button adjustable / step attenuator"
Regards,
Martin
