Howdy,
After lurking around for the last few years I had to Officially join this
Reflector, if for no other reason than to thank all of you for the wealth
of useful information I've read here. I start every day wioth a cup of coffee
and a look at the Top Band Reflector.
I do have a question for the group. At W0ZT's contest station he has a
DX Engineering Receive 4-Square array for 80 and 160. Last year we lost one
of the active antenna boxes (ARAV-1P). I assumed the failure was due to
lightning.
This spring I took the whole system apart and stored it all inside the building.
Last week we were very disapointed to find that TWO of the active antenna boxes
had failed somehow. Operating the CQWW without a receiving antenna was
challenging
to say the least. Some of the Europeans, EI2CN and OX5AA in particular, had to
have
tremendous signals to exceed my noise floor.
I'd sure like to avoid continued failures with this system. Assuming the
problem
is static discharge killing a high impedance input, how about adding an RF
choke
between the antenna and ground, say 2.5 mh? I know that would drain any static
charges off but would it otherwise affect the performanc of this 4-square?
Thanks in advance.
