[Elecraft] [OT] Birds and DX

[Dave]

Victor’s idea is very good. Some kind of material to create spikes, or a surface where they cannot perch.

II think the cat would want to wander the neighborhood ;-)

If there is some way you could attach spikes to the top surfaces... maybe superglue broken glass to it? Or wrap it with fiberglass insulation, or use that plastic stuff used to protect kids from the supports of a swing set to make it too fat for them to want to sit on.

The loop tunes to a near perfect match (1.00:1 SWR) but becomes instantly detuned when a dove perches on top of it.  SWR jumps instantly to > 3.0:1 and trips my High SWR monitor.    The birds look stupid but they are smart enough not to straddle the loop opening.   I imagine full loop voltage between their legs would de-tune them a bit but they just perch one side or the other.
