Re: End Fed antennas w/ uBITX #ubitx
I have the unit that was reviewed.toggle quoted messageShow quoted text
Have checked it over with a vector impedance analyzer.
It is resonant on 80,40,20,15,10 as claimed showing low SWR as described in the article.
Including 40 and 20, you claimed that would not be the case.
And very high SWR in most regions out of those bands, indicating I am not just feeding a resistor.
Your central point seems to be you don't trust the transformers.
Yes, many such transformers are quite lossy.
In the review, they put two matchboxes back to back, so 50 ohms to 49*50=2450 ohms to 50 ohms.
Then monitored power going in from a transmitter, and going out to a dummy load.
Found there was very little loss.
How is this methodology deeply flawed?
You say you communicated with the folks who did the review.
Would be interesting to see if they agree with you.
Have you looked at the particular antenna system in the review?
