• 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.

Because it has 2 seats, my S2-E requires an ELT to be legal. I have purchased an ACK E-04 kit. It includes a monopole, dual-frequency whip antenna (P/N E-04.8). My aircraft already has a VHF comm antenna installed on the turtleback just above the baggage bin. The ELT instructions say that the ELT antenna should be mounted a minimum of 1 meter from any vertically polarized comm antenna. This is going to be a problem...

Since the ELT antenna is a dual band with one frequency tuned to 121.5, is there some reason that it can't do "double duty" as a comm antenna in the 118-137 MHz band and simply replace the existing comm antenna?
