I'm working on a Log Periodic project.  I'm looking for a M2 42' long x 3" diameter boom.
If you have one, even if the total length is a bit longer, let me know.

I don't have an M2 boom, but for longer pipe, I go to irrigation supply yards. Pipe typically from 2"-5" diameter, and 50' is standard, although I don't recall the increments in diameter. The larger thick-wall stuff is often referred to as "torque tube", and is used in wheel irrigation systems:

If using it for a support, bases can be pressed on. Here's an example, some have four holes:

It's been a long time since I checked prices, about 15 years. At that time, 5" thick wall aluminum torque tube, 50', was ~$100 a stick.
