We have additional concerns below:
Could you check Ruckus P300 specification as below.
The catalog indicated “the P300 supports throughputs up to 500 Mbps and offers performance up to 100 Mbps at 8 km (LoS).*
* When used with optional external antenna”,
Appreciate your further assistance.
3. Get the pole mounting information.
You can find the mounting guide from the below link.
Some more good info about P300 you can find from below KBA.
I hope other forum members will help you with rest two questions.
