I spoke to Los Alamos back when Uni-hat first started advertising
scientists there tested the Uni-hat. I was puzzled by these claims,
since I knew Los Alamos had no facilities for measuring large HF
Not only that, the claims of "increased radiation resistance" reducing
dependence on a good ground were physically impossible. Any good antenna
engineer understands that.
To be sure I wasn't mistaken, I called Los Alamos. No one in engineering
there knew anything about an antenna test range for HF antennas.
Eventually they located a Mr. Wheeler, who was doing some personal work
with Uni-hat. Mr. Wheeler told me the Uni-hat was never tested at the
Lab, but he (Mr. Wheeler) did "borrow" a FSM from the lab and help some
guys measure FS on a Uni-hat antenna at a Hams house.
Mr. Wheeler also agreed that the radiation resistance claims could not
be true, and was sure the antenna was NEVER compared to a full sized
I received an e-mail from the owner of Uni-hat, and he claims the
antenna was tested at Los Alamos. I'll look into that claim further, if
he supplies the name of a contact at the Lab. Perhaps Los Alamos'
employees do not know they have a test range.
As it is, the only person at Los Alamos who knew anything about the
Uni-hat was NOT a scientist. He claimed the antenna was never tested on
a real test range site, and was never compared to a full sized antenna.
But perhaps Mr. Wheeler and others were mistaken. If I find out they
were, I'll post a correction of the facts.
