I had trouble with my antenna , you know SWR at just around one to five ,  so bought a Zetagi TM999 matcher ,  bobs your uncle now down to one to one.  Happy days.  Very Happy

What you have done is matched the impedance of the radio to the antenna, presenting what looks like a perfect SWR, and allowing the radio to deliver full power to the load.  If whatever was causing a poor SWR was a fault or poor match, it will still be there, and possibly hurting your efficiency.

Mind you, not sure whether you meant 1.5:1 or 5:1, as 1.5:1 is fine, and you won't see any difference in real terms between 1:1 and 1.5:1....all a true 1:1 means is perfect (resistive) 50 ohm impedance and no reactive component, which is hard to get unless you are building the antenna to do that in your environment.

Exacltly what I said but more long winded  🤔

Not quite - you said "lie to the radio", I said "impedance match". 

Anyway, I do apologise for daring to offer an opinion on your forum where you are clearly the only font of all knowledge. Rolling Eyes

I'm from London, and you in no way intended that as a joke.
