[ICOM] Fw: RE: AH-4

[D C Macdonald]

I would add to Icom's recommendation that you "shield"
the AH-4 on top and sides, but leave bottom of that
"enclosure" open.  In 50 years as a ham, I have basically
learned that you can't keep water out and it is best if
you offer an easy exit for water that does get where
you don't want it to be.  As for the AH-4 itself, I would
say that basically what you want is a "splash shield" made
of some plastic material.  There are lots of inexpensive
containers of various size made by a company named
"Sterilite" that are available at Wal-mart and other general
merchandise outlets that might prove useful.

73 and good luck,

Good Morning
Thought you guys may be interested in the reply that I received from
Icom regarding my question at the bottom of the page. Are you guys
using a weather proof enclosure?

Good Morning.....

Thanks for your e-mail.

We don't recommend mounting the tuner inside because from the tip of the
ceramic insulator outwards is the radiating element, so your feed line
becomes part of the antenna. What that means is that you will have
stray RF inside of the cabin of the vehicle, and this is not good for
the people that ride inside nor is it good for the systems of the
vehicle. It would be better to install a longer antenna at the rear of
the vehicle and mount the AH-4 outside in an enclosure. Hope this will help.

Best Regards;

Good Morning
I am thinking about purchasing the AH-4 to use with the 706 in my
Cherokee. Since the AH-4 is advertised as being weather resistance
instead of weather proof, I would like to mount it inside with the
antenna staying in the center of the roof. This means that the cable
from the antenna to the unit would have to be approximately four feet
long. Does this propose a problem? I am planning to use a 102 inch steel
antenna (CB). Will this be a good setup and will the antenna load ok on
six meters? I will use a Super Hustler for eighty meters.
