Both the ZRP5 and ZRP6 have the ability to hook up a RM433 antenna and a zigbee antenna. So you can use standard RF with either one but you'll have to purchase it seperately. Just keep in mind if you have a zigbee remote it will not output RF and vice versa.
On a side note, be leery about the ZRP6 and two-way. It is very limited and make sure you are aware of what it can do before you make promises.
