New Antenna PolyPhaser ?

[WSHI857]

I am getting ready to install a new Comet CA-712EF,  i will use the heliax cable 1/2" into a poly phaser then LDR-400 to my equipment.

My question is what Polyphaser do I need? if anyone can point me in the right direction. Is this the only ground I need to bring down from the antenna, I know I have to sink a new ground rod and tie that into the house ground.

Thanks

Gary

Whatever surge suppressor has the correct connections that match your heliax and coax. 
Typically you want the surge suppressor as close as possible to where the feedline enters your house. 
This is a good concise guide to the requirements:
