Please note that changing the connectors from SO-239s to N's will

Keeping something outdoors dry isn't a big issue. An plastic food container
will keep it dry. Just be sure to arrange the exit points for

I followed the link to confirm... note the heated Desiccant needs to go into
a sealed container warm. Amazing to see this stuff sent with so much stuff
that isn't sealed. What a waste and a hazard.

really waterproof, just somewhat resistant. And, the water doesn't

Fred,
I agree with your comments. The only issue is the small spiders and the
damage they can inflict. I lost a trail camera due to spider droppings.
Amazing the damage given a few years and the very super small openings they
used.
I want the remote to determine SWR at the remote tuner which

I'd be interested to hear from anyone who has waterproofed a sensor, I'm
considering the W2 and want to put the sensor on the masthead.

In the course of checking the physical sizes of the K Line, I see that
the W2 is the same height as the KAT500 and the same width (or close) as
the P3, which leads to the following question.
Is the W2 useful with the KPA500/KAT500 combination or would it be
redundant?

Even if you are running barefoot (amp in standby) the LCD window on the
KPA500 is functional and will give you a numeric power out or SWR if you
choose. No need for the LED's.
I'll be looking to sell my Autek WM-1 SWR meter at Dayton this year as I
feel it is redundant now.
