Using an LNA
Posted: Wed Jan 23, 2019 3:21 am
Hello All.
From what I read and hear the closer to the weather antenna you put your LNA the better. Is this correct?
The reason I ask, I really would like to put my Turnstile or QHA on top of my amateur radio mast, which stands at 36ft. I am surrounded by some obstructions ,but 36ft would clear them.
On top of the mast I have a 5 element Yagi which allows me to put 500 watts out. If I had the LNA strapped to either WX antenna then in turn the wx antenna strapped to the mast probably about 2 feet above the Yagi would I fry the inner of the LNA even if it has an aluminium casing.
However if I joined the coax to either antenna ran the coax either into where my RSP1a is (obviously inside my shack--Bedroom!!!) a distance of 10 meters from the top of the mast, then attached it to the LNA, would this be okay or will I have another problem.
I could also run the 10 meters of coax to under the house, attach it to the LNA, then run another 5 meters to my RSP1a.
Some help on this would be greatly appreciated.
Regards,
Jim.
