Darrel,
If u haven't seen this chart, here's a convenient way to compare cable
losses and make tradeoffs before investing lotsa $$$ in new coax.

There are several versions, and you might want to take this to
rec.radio.amateur.misc., where it comes up about twice a year,
always with inconclusive results.  Some of the more convincing
answers have been proved wrong factually, which doesn't stop
them being posted every time.

The answer I like the best is that it stands for "Have Any Mail?",
which was Craig Shergold's daily question to the mailman...

This has probably been hashed over before, but would someone post insertion
losses for connectors and splices (barrel connectors, etc)?

Thanks!

I can't believe what I think I am reading here.  If the proposed legislation
goes through, it sounds like it will illegal for a community to prevent the
installation of an unsafe tower!!  What am I missing?  As the owner of 4
towers and a Rohn dealer, I could possibly benefit by such legislation but I
would NEVER favor it.  Nobody should put up an unsafe tower and there should
be laws against it.  I HAVE, however, seen a lot of so-called "safety
arguments" against towers that are just plain BS.  If someone is going to
claim a tower is hazardous, they should be REQUIRED to prove the hazard
really exists by citing examples of known failures or demonstrating a hazard
exists by doing an engineering study that proves it.

Legislation that prevents a community from disallowing a tower on asthetics
grounds I would fully support . . .

Any contesters out there using the AL-80 Amp?  Sounds like a descent amp
from the catalog paragraph.  Curious about fan noise, etc.  Please reply
direct and I'll summarize for those interested.  Thanks.
