SWR 1.7/1 safe to use with Flex?

  • Updated 3 months ago
My 40 M dipole is very funky, with the legs only about 60-70 degrees apart due to the geometry of the property and so forth.  As a result, the minimum SWR on the antenna is 1.74/1 (measured with LP100A).  Is this safe to run on the Flex using the ATU?  Is it safe to run with a small linear NOT using an ATU?  My amp seems fine with it (Tokyo Hy-Power HL 1.2Kfx) but I am used to my 20-10 Steppir which always turns in a 1.1/1 or better SWR on the higher bands. I'd appreciate comments from my more technical colleagues.

Hi Roger
I had a similar helpdesk  ticket asking this question and I asked Gerald. Basically, 1.7:1 is not a problem. I think the transmitter of our radios is pretty over-engineered and you can feel comfortable that its fine.

It is always best to have the SWR as low as possible, How ever to your question, If the SWR is to high your Flex will fold back to protect itself. If it gets really bad then the radio will stop transmitting. It is really hard to damage these radios.

You say your flex has an ATU then for sure it's not a problem. But even without ATU having an SWR below 2 is ok. The radio has a protection that when reflected power is too high it will reduce output power but that's when SWR is even higher than 2
For your amp it's the same, below 2 your fine

In 50+ years I have never owned or operated an amateur transceiver or transmitter that did not function perfectly well with an antenna SWR of 1.7:1.

Thanks to all who contributed this valuable info to this thread. First time I couldn’t dip the SWR below about 1.4/1. Appreciate this great community!

Even a wet noodle gets out but you might be happier with another antenna design.

I agree, but this is the art of the possible and 40M is a stretch at my QTH, as at many QTHs.  Been working a lot of DX with this antenna and getting OK signal reports, so it is what it is.  Not all of us have QTHs where we can put up towers, beams, or a big wire antenna farm.

Roger, do you have a tower at all?
