• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

I know we have had significant discussions about putting Com antennas inside the fuselage, but I am contemplating doing it with the transponder antenna. Since I have the fabric off of the back of my fuselage, now would be the time to do it.

I was thinking of a ground plane attached to the bottom tubing with adel clamps and have the antenna pointing straight down, it would be below the tubing but inside the fabric. There appears to be about 3.5" and the antennas are just under that in length.

Any thoughts or experience?
