1.Where is the best place to put my Sunhans external antenna?

The external antenna should be placed at the highest point in your house in order to “catch” the signal as it goes by. This could be in the attic or on the roof. We advise against putting the external antenna too close to the base unit. The external antenna should have at least 15 feet of vertical separation from the base unit.  


2.Can I install a Sunhans myself?
We have designed Sunhans for easy setup. We have included instructions for each product both in the product package and on our website.
