Restricted airspace and lower limits

Question

I am a new UAS pilot who will be flying agricultural fields. Naturally, my first flight location is close to a restricted airspace for military practice. I want to make sure I my flights are compliant.

R-6904A is listed as having a lower limit of 150' AGL.

If I stay under 150' AGL, then I am not technically entering this restricted airspace, correct? Would I need to contact or notify anyone about my intentions to fly if I ensure I never exceed 150' AGL?

There are additional restrictions nearby in zone R-6904B. Here, the restrictions list as starting from the surface. I will never need to enter the area controlled by this restriction, so I should be good to not notify anyone about my flights, right?

I appreciate the help.

I would notify ATC anyway. I mean, there's no reason not to, right? — HiddenWindshield, Apr 04 '22 at 17:37
@MichaelHall If ATC knows you're there, they can warn you about other planes, and warn other planes about you. And air traffic controllers would much rather be talking to you than not. — HiddenWindshield, Apr 05 '22 at 00:32
@MichaelHall ...I somehow completely missed that this was for a drone. Ignore me. — HiddenWindshield, Apr 05 '22 at 01:10
No worries! I was kinda wondering where you were coming from... ;) — Michael Hall, Apr 05 '22 at 01:11

Correct.

No.

Right.

Added info -- the airspace in and near these restricted areas is Class G airspace up to 1200' AGL. If the airspace at the altitudes where you intended to fly were other than Class G, then under FAR 107.41 you would need to obtain prior authorization from Air Traffic Control (ATC) before flying your SUAS there (e.g. on-line authorization via the LAANC system), regardless of whether or not you were flying in a restricted area.
