@davep@infosec.exchange @dtl@8bitorbust.info @a2es@mstdn.social Yes, yes it is, the gain will be less by (waves hands) "an amount" for the lower frequency, but I'd expect 30-40db maybe.
If I could remember my college education better I'm sure I could calculate it.
This is the problem with not doing any college this century.

@Extelec@mstdn.social @dtl@8bitorbust.info @a2es@mstdn.social I found a calculator (no idea if 65% aperture efficiency is in the right ballpark). Using a 1.2m dish isn't great, but you could potentially do crimes at 433MHz with a bigger one... https://codingace.net/general/dish_size_and_gain.html
