I have a discone antenna on my roof and the mast is grounded to the
earth with #8 solid wire with a ground rod.
I want to use lmr-400 wire for app 50 ft to the scanner. Is it
necessary to install the cable with an in-line arrestor ? I hate to
have to add more connectors if it isnt necessary...I always unplug the
scanner from my cable, rg-58, when Im not using it.....Any
thoughts.....Thanks Mike

up to you really
but i'd be very carful about following the old wives tale about
disconnecting your coax during a storm.
this will then charge your coax with static that will discharge through your
equip when you reconnect it.
a shorted connector to a ground line would be much safer, if you wish to
disconnect

When I disconnect my antenna, I attach a 50-Ohm terminator to the free end
of the cable for the purpose of continuously discharging the
naturally-ocurring electrostatic charge.

Why not just leave a 10K or so resistor connected full time to the antenna?

What would be the reason for this? The receiver already has an impedance to
ground (2.2K in my AR8600 MkII), so it wouldn't be needed when connected,
and when disconnected, an inexpensive 50-Ohm terminator with the proper
connector is super easy to connect. Connecting an external resistor as you
suggest would require custom wiring (easy, yes, but why do it if not
necessary?).

Install a connection inline with coaxial cable that connects to ground. RS
may carry device. Has male/female ends with attaching point for ground
lead.

Is a 50 Ohm termination a special value for static discharge? Is it better
than a short or a 10K resistor? The permanently connected 10K would make it
unnecessary for you to screw on your 50 Ohm termination.
