1. [AMPS] Where to read Reflected Power (score: 1): Author: jreid@aloha.net (Jim Reid); Date: Mon, 27 Sep 1999 13:53:28 -1000; Hi, Was tuning up for some CW on 10 meters today. Decided to also use my linear, Henry Ultra. This amp comes with a Bird coupler on the back of the RF deck.

I had the same situation and discovered an article in QST years ago that the problem was poor directivity of the SWR bridge (discrimination to power coming from the reverse direction).

At 10m, many of the HF type characteristics begin to break down and you are nearly into the VHF region anyhow. Line lengths, etc can become more important.

If a 15 to one / 750 ohm antenna is connected to a matching network/antenna tuner, the 750-ohms is transformed to 50-ohms +/- j0 ohms. ?

The impedance at the feedpoint of the antenna does NOT change because you put a tuner in the line. If you think that it does, I have a bridge to sell you.

Yes, it does transform the impedance. The conjugate match is between the exciter and the tuner.

Ok, that aside, for precision weak signal ham work in the VHF/UHF range, I'll agree that a 15 dB return loss isn't great. However, there ha; /archives//html/Amps/1999-09/msg00289.html (10,178 bytes)

An antenna with a 750-ohm feedpoint impedance, fed with open wire line through a tuner and balun, could be a very *good* antenna, indeed.
