Unfortunately the Series 4 stick grip document remains unpublished to date. Thanks to the great guys on the 'List, I got the documentation within hours, and was able to deliver the schematics on time !

Exactly how much can only be determined by testing. You can install the antenna then go fly and try it out. You might be satisfied with it. Or maybe not. An option is to mount the com antenna on top of the airplane. Theoretically the airplane will block the signal from reaching the ground. But in practice, top mounted antennas work fine. The same might be true for an antenna mounted between the gear legs. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=470234#470234 ________________________________ Message 4 _____________________________________ Time: 10:36:01 AM PST US From: Robert McCallum Subject: Re: AeroElectric-List: com dual PWR/GND on two fuses? Always bear in mind that the fuses are sized to protect the wire and what is connected at the other end (in this case your radio) has no influence on the fuse size used. As long as the wires are adequate for the 10 Amps then 10 Amp fuses are fine and certainly if the existing wiring will supply the new device's requirements then they may be reused/re-purposed.

Hi Bob You are right that the fuse is there to protect the wire, but the size (in A) of the fuse is a function of the current which is drawn by what is connected at the other end of the wire, isn=99t it? Otherwise you could put a 1A fuse to protect a #24 wire with a pitot heater at the end, and you would never see that heater working when you wanted it.

Bob McC ---------- Original Message ---------- From: Werner Schneider > > Hello, most avionics do have PWR and GND on two pins. My SL30 had even one used for the NAV part (3A fused) and one for the COM part (5A fused). I have to replace it with a new 8.33, but just going for a COM right now, that one has as well 2 pins each tied together, PWR onto a 10A fuse (8W COM). Is there any disadvantage, if I use the existing cabling with the 2x GND/PWR on extra fuses? Should I use 2x10A fuses (for a 8W com I found the 10A a bit high). Thanks for your advice Cheers W-======================== ========= > ________________________________ Message 8 _____________________________________ Time: 04:02:21 PM PST US Subject: Re: AeroElectric-List: com dual PWR/GND on two fuses? From: Kelly McMullen Not Bob, However, the wire has to be sized at a minimum to carry the anticipated load, so you would not have the situation you describe. On the other hand, it is common that relatively small loads, say 1 amp are carried on 18-22 gauge wire, and would be fused for what the wire can carry, usually more than what the load is. Another common occurrence is that wires for lighting on a plane were sized for an incandescent load, but the lamps have all been replaced with LEDs that draw 1/5th the amount. The circuit breakers would not change, because the wiring did not change.
