No doubting the enthusiasm of the authors, but the article does give rise to several interesting points. First, they totally neglected to initially determine the LC constant of the matching network,

Agree... The authors enthusiasm for operating 160M was undeniable, despite the technical errors, and may encourage others to try the TopBand, particularly those with outside antenna restrictions or
There are many many technical errors in that artical, incuding stuff about gain, impedance matching, grounding, currents, voltages, etc. But the content about balloons seemed useful to me, and I thin

We used a full wave loop at KC8MK (now K8MK) in several contests. Top was supported by a French military kite (altitude = ? we had out > 750' of string) bottom was supported by 2 50' push up masts. I

If this is true, why do the stations located on the edge of an ocean (some of which you have operated from) have such an advantage? The majority of the ocean enhancement is at the lower angles of rad
Article also had a good picture on how "Not" to wind a coil. And from the look of it, it was woefully lacking in the required inductance for a parallel R/C network. May explain why the bandwidth was

I ran some tests recently on 160 with VK's and ZL.'s (and a few other directions and distances). After the tests, I tallied the results. It's easy to see the wave angle is a lot lower than people sp
