Good morning all

First of all, I'm sorry about some missing answers ... If only days had 24 hours and nights another 24 ...

The measures looks promising. The inner wire looks right having the right measure and I'm thinking in two possibilities for the outside element, or is a complement from the wire making this a funny designed antenna or is what we spoken before - a ground plane ...
Either way, looks that this antenna is not that chinese mumbo jumbo antennas with lot of plastic and almost nothing on the inside, I'm guessing that this would be a "real deal".
Better than this is like Werk_AG says, testing with instruments ...
Maybe we should open an testing lab just for this and accept samples to test, any volunteers?

As I said here, these are my prefered for TX. I'm using one in each of my two TX units.

This is just my opinion, based only on practical results, I don't have dedicated equipment of knowledge to do more specific tests (Gain, SWR, etc).
Let's see if Meteoestarreja has something to say about it.
