Right now a wire antenna. Likely all I will use here is a wire antennas and or a vertical one, of one sort or another. I didn't really know at the time I wrote this that tuners were so expensive. I thought a tuner would be easier than monkeying with radials and different Unun heights. I have an DxExtreme 88' end fed antenna that gives me problem especially on 75/80 meters. 5 to 1 is the best I have been able to get. I had it as a sloper at first and it was not good there, so I reset it to I guess a horizontal "L" if there is such a thing. It parallels the ground. Unun at 20' sloping up to 35' at the pulley, and does a left turn sloping down to 30'. I am using LMR-400 coax. Suppose to do all bands HF 160m to 6m. It is really not working all that well as a multi band wire antenna. It's probably a stretch to expect good SWR on 10m and 80m.Well let's start with the misnomer 'antenna tuner'. A TRUE antenna tuner is at the feedpoint of the antenna and uses a shot of RF to tune the radio to the antenna. For example SGC makes some very fine ones but they are mucho expensive.
What you are likely looking for is a transmatch. For what kind of antenna? Coax or ladder line, or both? Frequency range? What are you trying to tune? Be specific here

OK and again the built in tuner in the 710 isn't working? Unless I'm mistaken you got a FT710 and it should have a built in tuner.Right now a wire antenna.

Yes it's working but it only tunes 3 to 1 or lessOK and again the built in tuner in the 710 isn't working? Unless I'm mistaken you got a FT710 and it should have a built in tuner.
This is relevant due to it may change the recommendation for an external one.
How much room do you have for a wire antenna? If you have 133ft an 80-10m EFHW or OCFD will give you a good match on all bands 80-10m except for 60m. The shorter 64ft version has a good match on 40/20/15 and 10m. The 3:1 tuner in your radio will take care of any problems and these antennas will radiate a better signal than your non resonant end fed and will not have RF on the coax like you probably have now.Yes it's working but it only tunes 3 to 1 or less
MyAntanna's EFHW-7510-2K-Plus will be here this week. Yup lots of RF coming off that the coax. I have myantennas choke CMC-154-3K 1-54MHz at the radio, as the DxExtreme say not to use one at the unun.How much room do you have for a wire antenna?

Congratulations on the antenna purchase. The reason they don't want you to use a CMC on a non resonant unun type is because the coax is a radiating part of that antenna. You really need one but place it closer to the radio so you have some hot coax to help it work.MyAntanna's EFHW-7510-2K-Plus will be here this week. Yup lots of RF coming off that the coax.

This is likely the best answer to the problem you're having. If you can get that RF of the coax, that will be a great help.How much room do you have for a wire antenna?
