I have a Sigma-5 from Force 12 when Tom owned the company, and haven't really tried it out. Being retired now and having more time to play with antennas, and with the nice weather that we've been having, I'm having all kinds of fun. Just put together the Alexloop Walkham late yesterday.
Hopefully, the Sigma-5 will perform similarly to your Sigma 40XK. 72/73 de Jim - AD6CW On 5/11/2012 4:52 PM, Dyarnes wrote: > David and All, > > I have a Bravo 7K, and so far, I find it to be only a "fair" performer. > This assessment is based only on limited testing against my Sigma 40XK > vertical dipole, which is another N6BT design from his time as owner of > Force12.
