Antenna external mounting

Recommended Posts

Atosmarkyp

Hi All,

I'm trying to come up with a way of mounting my antenna ends externally on my carbon fuselage so that they stick out perpendicularly and don't get bent over at speed.  I've had this glider all ready except for the antenna mounting for 2 & 1/2 years and I'm wanting to finish and fly it.  I have seen some sharks fin looking antenna fairings on someones glider down in Dorset a couple of years ago and thought at the time that I needed to come up with something like that.  I've been toying with the idea of making some aerofoil shaped fairings / mounts that I could glue to the fuz so that they stick out perpendicularly but I'm not coming up with any ideas that have motivated me to try to do it.  Has anyone out there got any ideas of how to achieve this ?  Sorry if this has been asked before but I'm new to this forum and haven't been able to find anything that answers my problem.

Regards,

Mark

Or like this one I just printed with my new 3d printer . Printed flying wing next project after sorting a few things with the printer.

Hi Marc,

They have been sold out for the last 2 years.  Same as the ones that were on the glider I saw down in Dorset a couple of years ago, that chap said they weren't available anymore.  Thanks for replying though.

Cheers,

Mark.

Hi Geoff M,

That's excellent.  I thought about 3D printing but struggled to find the time to research what software to use to design what I wanted to make and produce the program file to get someone to make it.  Can you tell me what software do you use to produce this ?  And do you need to be a cad trained design engineer to achieve it ?  I was hoping to make some that were a straight aerofoil section so that they hold the antenna dead perpendicular to the fuzz, my glider is all carbon and I wanted to get the ariels out as far as poss for maximium exposure. 

Also, in the event that I can't do what I'm hoping for would you be willing to sell me some of your shark fin style ones to try ?

Regards,

Mark.

I did not design this. There is a web site called "Thingverse" that has thousands if not millions of different items already designed.  Do a search on "Shark Fin Antenna Saver"  . You can then download the design files for free . You then load the .stl file included in tbe download in to your slicer program .I use Cura.  Tbe slicer program produces G code which a 3d printed understands ,save this to a sd card .Then transfer sd card to your 3d printer and press go and wait 30 min for item to print.

That is the very bare bones of the procedure.  There are many settings and options and lots of howto's on the web. My printer is an Ender 3 Pro ,180 pounds.  I'm very much a beginner on a steep learning curve.

Happy to supply a couple. for cost of postage. But they will have to be blue as that is the only colour filament I have left.
