The material, thickness and placement all affect radome loss.
Fiberglass is normally the best, the thinner the better.
There is a factor called the loss tangent for most materials used. The
lower the better.
But it also has to be spaced such that it is placed in a null in the
nearfield electrical field.
If it is spaced wrong it can create a bunch of loss. Spaced right and it
becomes invisible to the signal.
I would say less than a dB and if done right, less than a half dB.

Subject: [AFMUG] Radomes...
What do you folks out there see for signal loss when putting a radome on
a 5 Ghz link? I was testing today thinking I might see 1db loss and
was surprised to see more like 2-3 db! I also had that link go from
doing 80mb/s in testing to around 70mb/s with the radome...
Best,
Robert
