YouTwist Antenna.

 

Hi Prog,
 
Very late to the discussion. How the YouTwist compare to the YouLoop? The fewer blocks to build, the more I'm interested? I have neither at the moment.
 
I accept a performance penalty for more simplicity...up to a point, of course.  :^)

The performance in HF is pretty much the same. No VHF in the YouTwist, which could be a good thing.

That's good. I'm first and foremost an HF guy.
 
Thanks,

One of the inherent advantages to the absence of the VHF response, is that you can put a preamp without worrying about the FM broadcast band, strong pagers, etc.
 

The concept of preamps at HF raises the hairs on my neck. "Somebody is wasting good money on really bad assumptions." As a teenager I fell for the preamp gag. I spent precious money on a DowKey preamp. I put it on my "draped over the rafters" pseudo-vertical for 15 meters. None of the signals improved despite being obviously higher level. When I got into college I found an interesting small book with a green cover about "Noise Figure". Despite being only a sophomore I read the book, understood it, and would have done something violent if I had a person from DowKey near me as I had my "Aha" moment.

The TL:DR is simple. If you attach the antenna and the S-Meter goes up, no preamp on Earth is going to make the signals more readable. And readable is what is important - unless you want to give 100dB over S-9 reports after actually reading that on an S-Meter as a way if lying without quite lying. Big antennas suitable for transmitting will always fit into this category. Very small antennas might end up benefiting from a preamp, which should be part of the antenna.

{o.o}   IMAO of course.

I  totally agree with this. The best way to get good SNR and signal discrimination is not having the antenna pick send you things you aren't interested in :-). So many articles discuss making antennas useful on wider bands and so few discuss making antennas that are really poor receivers outside of the band they are designed to receive.

That's what we are discussing here.

This will be useful.
