There shouldn't be any interference but you may want to place the Mode-S antenna away from any other ones to avoid any close shielding of signals by the physical antenna..

You can attach the Mode-S antenna to the existing mast.  Possibly set it away from the other antenna, as I have:

What antenna will you use to cover Mode-S, Airband and AIS reception?

Thanks.  I don't think that one will receive Airband or AIS signals.

Images do work.  How are you trying to post one?

Here's an example using img and the location link.

I drilled a hole through the wall.  Before I put the 10mm Ecoflex under a roof tile.  It depends on thickness of the cable and what options you have locally.

I was using google drive. They won't let you just link, you have to get a google+ account. I'll pass :-)

You should be able to get a shareable link:

And with a little bit of manipulation and Thanks to:

Hi Miguel, you can use a double arm support attached to your mast. That's how I have antennas, anemometers, etc (I'll take a pic of the real thing).

Or you can use a single wide-band discone type antenna to cover all the frecuency range you want. Anyway it will always be better to have specific tuned antennas.
