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.

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? -------- rck Read this topic online here: http://forums.matronics.com/viewtopic.php?p=231854#231854 ________________________________ Message 6 _____________________________________ Time: 11:18:51 AM PST US From: "Wayne Williams, MD" Subject: AeroElectric-List: XM coax 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. ________________________________ Message 7 _____________________________________ Time: 12:01:14 PM PST US From: "Robert L.

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.

Ron Parigoris ________________________________ Message 11 ____________________________________ Time: 06:31:24 PM PST US Subject: AeroElectric-List: Re: Using a key Ignition switch with a Rotax 912 From: "rckol" 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). -------- rck Read this topic online here: http://forums.matronics.com/viewtopic.php?p=231943#231943 ________________________________ Message 12 ____________________________________ Time: 07:21:27 PM PST US From: "Chris" Subject: Re: AeroElectric-List: E-bus and sd-8 alternator connections Z-13/8 Q Thanks, I'll press on. -Chris ----- Original Message ----- From: "Robert L.
