Tony, Go for it - my 'Europa' aerial has worked well in 5 years of flying around Europe. I fitted it including the soldering, but had it VSWR checked as per the book. I am no expert on the subject and if you read through the database of previous emails you will certainly get a variety of very clever and technical replies. However, I can only speak as I find. regards Steve Pitt G-SMDH XS Trigear with King KY97A radio ----- Original Message ----- From: "Tony Renshaw" Sent: Friday, October 21, 2011 1:23 AM Subject: Europa-List: Coax Advice for VHF antenna. > > Gidday, > Ive got a bit of a hybrid, a classic with a few bits of XS thrown in.

The latter is a compromise to save space in case your airplane is too small to fit a decent half-wave antenna (dipole). A dipole is the most "natural" radiator. It has 100% efficiency and produces a toroid radiation pattern, which is exactly what you need in an airplane. If an antenna-manufacturer claims gain over a dipole, it means that it has gain in a certain direction but also losses in other directions (they often forget to tell you that). Consider the antenna as a light bulb. Sure you can produce gain in certain directions, but regardless how you do it (lenses, reflectors) it also implies you create dark spots (shadows) in other directions. Which is fine for a static setup but not for an airplane. As a dipole radiates 100% of the energy, it is not possible to create any antenna that beats this AND retains an omnidirectional pattern at the same time. Also, another advantage is that the dipole antenna can be placed further away from the cockpit and tailplane assembly, which minimizes interference.

You might like to have added that those chosing to bypass Belgium could be persuaded to stop and spend money in the Country if it were not for this charge. I am surprised that this has not been taken up by the CAA/LAA/Charles Strasser/AOPA or someone in that vein.

I also found the Europa antenna perfectly satisfactory. Soldering the coax fitting to the coax cable can be tricky so it is important to follow the assembly instructions to the letter. They should be printed on a label inside the packet containing the coax fitting. If you cannot find it let me know and I will e-mail it to you. A crimped connector is much easier and produces a more consistent result but you have to buy a crimp tool!

Many thanks to those responded with a variety of good advice. A gre at team effort enabled me to return to the aeroplane equipped with a comprehen sive list of potential causes and solutions. I was able to quickly work through the list until I found the problem and fixed it. >From the team I am able to award =93The Man of the Match=94 to Neil France for his recollection that he knew someone who had a similar problem caused by a bad earth to the ignition solenoids and sleeves=94. Whilst re-installing the engine I had replaced the fuel pipes and the carb heat pi pes before reconnecting all of the earth leads. This left no room to replace th e earthing screw and leads in the original position. No problem! I connected the battery earthing loom to a more convenient position on the engine=2C and th e ignition earths to another handy position. Retrospectively=2C I can see that the group of ignition connectors alone are thinner than the original group=2C and somewhat oxidized at that. The earthing screw had shouldered before clamping the earth leads causing an inadequate earth. Easy when you know how=2C isn=92t it? I did find the info. sent to me really useful=2C and I have it in mind to create a flo w chart from it all=2C which others may find useful with fault finding for ro ugh running in the future. It is more common than I thought. Thanks to Ivor Phillips=2C Bob Harrison=2C Duncan McFadyean=2C Dave Watts=2C and Barr y Tennant. ________________________________ Message 11 ____________________________________ Time: 10:19:17 AM PST US From: "Max Cointe" Subject: RE: Europa-List: Re: Toe vs Finger Brakes Hi Juergen, Our levers have been extended by almost 10cm.

So much specific know how in just two replies! Today I inspected my brake setup and found it like Max expected. The toe brakes have been converted. That means screwed together and fixed anyhow. First I will try to adjust the fluid quantity. and perhaps will build longer levers. But the first problem I have to solve is getting access to the lock screws as there is no opening in the cockpit. All in all not a big peace of engineering. Will come back to you.
