In looking things up it appears radials will have macimum voltage at the ends, so I’d make sure you have good insulators there; can you stand them off the house so they don’t move in the breeze?

This may be too much info but you can digest this:

The docs for my antenna says that if radials are longer than the length of the roof from the antenna to the edge, they can be draped over the edge and allowed to hang down.

Two of the radials I will install are 33 ft long but the house is only 45 ft wide and the antenna is right in the middle and at the top of the roof, which means 10.5 ft of the radials will hang from the sides of the house.

My read of this tells me that if I am using insulators, I should bring the radials to the insulator, through the holes and loop to secure, then let the rest of the radial hang down from the side of the roof.

Is this correct?
