I wondering if the any of the characteristics of the cage monopole will be much different at AM BCB freqs, or if the cage will appear as a single element to the large wave lengths in the AM band.
I’d be inclined to treat it as a single, large diameter vertical element, as my first try…
1) How do we attach the wires of the cage to it? Have a top and bottom ring that shorts all the verticals together and attach to the bottom ring?
2) How to measure for a match? Same as with any ANT – check the4 current going to the ANT – the better the match, the more current flows
3) Will matching with the coil and whatever else (air cap?) to get it to resonance kill too much of our minuscule power? Should need much less coil, should be less resistance than a thinner radiator, air cap would be the same.
