Hi All,

I’m looking for advice as to whether I’m being too precious with SWR and in doing so, costing myself Watts.

Across most of the frequencies I use, I have an SWR of 1:1.
Max 1.4 : 1 at the high end of my rig’s range.
I have a Zetagi TM999 in-line which is a Wattmeter, SWR meter and matcher all-in-one.
Now, when running low power, SWR of 1.4:1 would not bother me enough to use the matcher.
However, when running a linear, I use the matcher to pull it down closer to 1:1.
However, upon doing so the Wattmeter falls from 80W to 60W, (as example).
Probability not the most accurate meter, however, am I concerning myself too much with the SWR v’s the linear’s transistors?
Would you guys just roll with the 1.4:1?
Is it even worth using the matcher for 1.4:1 ?

Any thoughts or advice greatly appreciated as always,

Smile

Thanks NUBSTER,
Yes, it just “creates” a match. (Absorbs the reflected power, by minor tweaks to impedance I assume........)

Thanks for your reply.

All the tuner (Really poor name for them, BTW!) is doing is presenting a near 50 ohm load to radio, nothing more.  The SWR between tuner and antenna is still whatever it was before.

People will argue all day about the efficiency of resonant vs non-resonant antennas, so I won't even go there....  Very Happy

The best tuner in the world can't adjust the physical length of the antenna.
I just fools the transceiver into seeing a 50 Ohm load.
I think i am correct but i could be wrong as i am falling to bit's
