Right on the nose, Jim, and they don't have to be expensive 
either,....the ones I use are from HAMTRONICS (assume they are still 
in business).  they are at least 20 years old, built from a kit, and 
mounted in a wx proof box at the antenna, still functioning 100% and 
as I remember about 18 bucks at the time.  They outdid  others on a 
side by side coax switched test, and needless to say the owner of the 
"big time charlie"was not too happy!!  Hamtronics has pre-built for a 
few bucks more, or did at that time...Use them, and hang just about 
any kind of antenna on for what we have flying now....One made from 
coat hangers would work just fine...And I've said this before.....low 
loss coax, and prime connectors properly attached.

I see the "antenna discussers" on here having the time of their life, 
and more power to them, probably on of the most fun parts of ham 
radio for some of us, but don't forget to include and calculate LOSES 
in the entire system.  Your most magic antenna can go down the tubes with them.
