[time-nuts] Practical Survey-In Accuracy?

[Bob Stewart]

Hi Attila,


Is wood, nails, and asphalt shingle really that big of a problem at these frequencies?  The antenna is within 2 ft of the highest point of the roof.

A choke ring will not help you much in the attic. You already have lots
of reflecting and refracting surfaces/volumes above the antenna.
Unless you get to the top of your roof, i wouldn't bother adding a choke ring.
