This time in a Cherokee. Read the story that is titled "Best Short
Feature".

Wouldn't happen in a Bob Nuckolls inspired OBAM aircraft.

What does the installation recommend? You can get sma connectors
for about any of the popular coaxes. If your kit came with
connectors, then you'd need to know which versions were supplied.
Their is a high probability that any connectors supplied will
be compatible with the common preference for RF-400 or RG-141 coax.
However, it is possible that some other product fits your connectors.
If no connectors are supplied, and no recommendations are cited
in the manual, then RG-400 and compatible connectors would
be my guess . . . although there are some new, lower loss
coaxes that would work well at those frequencies.

I've pondered this a bit . . . I think you will
be okay with that modification.

Bob,
For a pitot heat relay would a P&B VF4 style 30amp (Digikey PB687-ND) relay
be suitable or would a solid state relay such as Perihelion sells be better?
Thanks,
Stan Blanton

I have decided to use a keyed switch for the starter contactor only, as a safety
measure, not a security measure.
MacMaster-Carr has small and inexpensive keyed security switches available in a
two position SPST momentary contact version that would seem to do the job.
http://www.mcmaster.com/#key-switches/=qsw33
Has anyone had any good or bad experiences with these?

Bob:
Thanks for the reply. I apologize for my misspelling. It should have been
XM (not EM). It did not come with any connectors but I did find out it needs
to be 50 ohms. The supplied antenna has a permanently connected cable the
size of a single shielded wire. I'll try the RF400. Thanks.

In single engine aircraft, this device probably has
the lowest operational duty cycle of any other
accessory . . . no, second lowest. The baggage
compartment light is lower.
Some form of relay is useful because the popular
toggle switches are not well suited to the peculiar
warm-up current profile.
The VF4 would be fine . . . as would any other
device rated for this service.

What are your concerns? As a safety switch, it never
has to SWITCH a load, only guarantee an open or close
circuit exists before the starter button is pushed.
This is about the most relaxed duty you can require
of any switch.

How long a run from receiver to antenna? RG-400 is noteworthy
for it's stiffness. How important is it that the wire have
some degree of flexibility? Is there receiver permanently
mounted to the panel?
Also, is the supplied antenna an "active" device? Many GPS
antennas have pre-amplifiers built into their bases. You need
to be sure that any proposed replacement antenna will perform
as needed.

Any recommendations for camera to be mounted in vertical fin?
I have a Europa XS and want to mount a camera forward facing in the rudder
cap. It is about a foot forward of a Bob archer SA-006 big "E" antenna.
Thx.

I had it in mind to use the momentary contact version of the key switch to replace
the push button starter switch, so it would actually be switching the current
to the starter contactor.
My concerns are whether these are quality items that would be expected to perform
well in the extremes of temperatures that it will see (Wisconsin winters to
desert heat).

Hi Michael, This is Ron's building partner Wayne. Thanks for the
lead here, I was reading through the forum on chaseCam and came across the
VHF radio interfearance post. The company is working on improving
EMI and they don't currently have any UL or CE ratings; did you notice any
noise when operating your system? Thanks, Wayne
