Flew 224xs NYC - LAL - NYC almost all IFR (actually under the hood mostly, but some IMC) Funny thing about the wind, it was always on the nose. All told about 18 hr of flying The show was very nice indeed. About 8 Europaphiles converged at the local Hooters for a round of drinks and good cheer. The Armstrongs also had their Europa on the Flightline. Andy manned the company booth and showed the flag and there seemed to be good foot traffic. I had the pleasure of having Andy fly with me and after some fits and starts on the ground including overheated brakes and runway closed by an AT-6 with collapsed gear. Andy pronounced that 4XS flies like a Europa (but perhaps a bit faster ;-) ). On landing, we had a hold at Lake Parker followed by a go around command at 100 feet. I had had a rudder trim issue at high cruise (140 145 kts) which he fixed for me as well. The only problem of my trip occurred at Chesapeake Regional on the return leg. The wind was 40kts + and when I opened my door at the fuel depot, the wind took it out of my hand and snapped it against its tang stops. The strut was torn cleanly off, the hinges bent and the tangs delaminated. We continued the flight home as the FBO was closed, the wind was horrible and freezing cold. Anyone else have this happen? What type of repair was needed?

I want to avoid putting it exposed under the belly. My likely choice is a Microair T2000 and I would like not to have to spring for a Bob Archer ($$$), but am told that the stub antenna must (should?) be mounted externally. I've read everything I can in the archives, and asked the UK supplier of the Microair, and still get several different answers. Jim Nelson wrote on 20 Jan 2004 "I mounted mine in the back on the pilots side. I mounted it vertical on three wooden rods which were reduxed to the fuselage. Ran the coax up the pilots side just under the door jamb and on to the transponder. Seems to work fine. No interferance or noised noted." This seems the logical answer, is this the stub (2.5"?) antenna & can you elaborate on the 3 wooden rod mount, please Jim? Anybody know why I shouldn't mount the stub antenna internally (glass is transparent, isn't it?) behind the baggage bay, without being too far from the xpdr unit and without degrading the signal significantly?

I had serious problems with the polar diagram (ie poor operation) from 45 deg left of centre, through the nose to 30 deg right of centre. Caused almost certainly by the landing gear and engine shielding the antenna. Would suggest the best place would be on the lower surface of fuselage so that the antenna can "see" 360 deg around and downwards. My transponder was the Terra unit feeding a Terra antenna. Hope this helps.

The manual p.22-6 says to hook one end of the spring to an FL10 spacer bolted through the firewall at the front, but the other end to an OR9 spacer bolted to the CS21 (attached to the rudder pedals). The FL9 is a smaller spacer than the FL10 and the spring is kinda tight in the smaller gap; a good fit in the FL10 though. I asked Andy and he couldn't actually remember why different spacers were specified at the time the manual was written - maybe tight fit with the engine mount, but he couldn't be sure... we agreed it was best to just "build it as written & not worry" ... but I do!! (only intellectually...) Any clever ideas why the difference, please? Paul M Mono XS 383 CM etc in, top on next Book yourself something to look forward to in 2005.

I have a simple 'lollipop style' antenna built into a fibre glass moulding, with ground plane. It sits on the left side of the fuselage floor, just aft of the baggage bay. The transponder is a UPs/Apollo SL 70 and it has worked well right from the start without any apparent blanking problems at all. regards, MP ----- Original Message ----- From: "Colin John Howard Richardson" Subject: Europa-List: Transponder Antenna > --> Europa-List message posted by: "Colin John Howard Richardson" > > > The original position of my antenna on a mono wheel was mounted on the > back of the baggage bay with the lower end of the antenna about 3inches > (75 cms) above the lower fuselage . > > I had serious problems with the polar diagram (ie poor operation) from 45 > deg left of centre, through the nose to 30 deg right of centre.

Aerial was a sharksfin shape from Aircraft Spruce. Additionally, if you mount the aerial near the occupants you will be subjecting yourself to continuous radiation (unlike the comms radio which only transmits intermittently, the transponder transmits every second and at a higher output wattage). If you are planning on fathering any children this is something you should consider (on a metal A/C this dosent matter because you are shielded but in a plastic A/C there is no shielding). In other words it would be better to mount the aerial near the back end of the A/C. If you do this however you will need to use lower loss (ie: larger diameter) coaxial cable). ----- Original Message ----- From: "M@nsfield" Subject: Europa-List: Transponder antenna > --> Europa-List message posted by: "M@nsfield" > > Planning what transponder antenna to fit and where...

Although one could argue that the water radiator blocks its forward "vision", this doesn't seem to be a problem. However, on one occasion the received signal was "dropping out" in a direction at right angles to the a/c longitudinal axis. This might have been due to the presence of the CF legs of the fixed TD undercarriage. This would be comparable to the tri gear steel legs. So, the aerial location may not be fool-proof for this type of undercarriage.

A transponder transmits for only 21.3 microseconds and only when interrogated by ATC. Therefore, even though high wattage, there's no harm even a foot away according to data published by our gov't. I calculated it as less than a typical cell phone at one inch from our cognitive matter.

I think the problem is the worst-case assumptions they need to make, then in-house counsel add a foot ; then outside counsel doubles the result! In addition to making no assumption as to how much power loss in your coax and your actual power output vs. the minimum specification, the safe distance is very much a function of how often ATC (and lately TCAS-equipped planes) are interrogating you. Then you need to assume all data bits are being sent (rare), plus an ephemeral ident bit even. The ARRL (ham radio types) has an online safety calculator, and realistic assumptions do result in inches of safe distance at even 2 interrogations per second.

For a dipole type you buy (Archer, for example), no either, unless mfr says to. For a dipole you make, yes, but one is unlikely to make an xponder antenna which works well, making the ferrite core moot.
