    It's not.

    Onno is not well informed on this 'foundations of amateur radio.' IMO.

    My sense is that Onno writes stuff up for himself, 'blogifies' it, and then poses it as a podcast. This is what writers do to learn their craft, sometimes. The problem is it is missing an editor (!) The facts are either wrong or not well posed, on more than one occassion.

    Nothing wrong with that. What's wrong is , with rare exception, his opinions do not jive well with facts pertinent to 'foundations of amateur radio'.

    For example, he is pushing running QRP moonbounce--on CW.....a horizontal fan dipole as a vertical, etc.

    And of course, such are not 'amateur radio news'.

    As Chip (who beat me to it already) said; it's not. The self-promoting clown who is apparently inept enough to drill holes in his own hand posted this highly erroneous "article" in the wrong forum and even included the wrong chart depicting a horizontal fan for starters.

    As I may have already pointed out in previous posts, fan verticals are great antennas that take up little space, can be multi-banded with one common feedline and are capable of very good performance when elevated above ground and include a good radial field---and unlike horizontal fans---do not need to be at least a half wave length above ground on the lowest frequency of operation for optimum results.

    As you wade your way through many confused replies in this thread you will find a few that refer to a vertical fan dipole, that, unlike Santa Claus, does actually exist.

    why not just buy a ALPHA DELTA fan dipole for 10 to 160.
    Had mine up for 15 years no problem.

    Why not?

    Because many of us do not have the capability of raising a horizontal fan to sufficient height for dx; a fan vertical is often a viable option for those who prefer low-angle radiation from something that can be erected at or close to ground level.

    That is certainly another way to do it but I suppose the tradeoff with this variation is the potential for loss in the capacitor matching. If the fan vertical is only for the higher bands (even 40m) it can be done without any matching or switching involved.

    All the hype about drills....what about soldering irons?

    Did you (that is, anyone) BURN a HOLE in your hand???

    How long did you have to hold it in position?

    OM, it used to be worse: wood-burning soldering irons were more common 50-60 years ago, and they had long, fat working ends with short grips. That's what my summer camp had out to solder knight kit walkie talkies....some looked like this....they were inefficient and needed the gawdawful mass to thermally maintain a constant temperature.

    I still have the scars ....

    but there is NO WAY you could hold them long enough to burn a hole in your hand.

    You should never be applying PRESSURE to the point of contact with a soldering iron. Touch and heat.

    Any injury invoking a hole in your hand means the injured party didn't learn/use basic safety steps.
