Honeywell galaxy RF portal dual antenna option

Hi all -

On a galaxy G2-20 I'm using an RF portal c079-2 , it's a model that uses tracks on the PCB for the antennae, and has a jumper with the 'russian' frequency option.

There are 2 antennae, one vertical and one horizontal - and a jumper to select 'ant1' or 'ant1 & 2'. The jumper was set to 'ant1' when I got it - not sure if this is the default setting, and there's nothing in the manual I have about it (perhaps it's only an installation manual).

Anyone know what the 'ant 1 & 2' jumper option is for, and when you'd use it?

Cheers
Iain
