You would have a big matching problem and the ground radials would probably dominate the vertical portion of the antenna pattern.

There can be issues with feed lines sometimes that affect the meters results, but the factors above are good goals. It is always best to take these readings for tuning purposes at the feed point and at the working height---albeit inconvenient.

This is a bit low in frequency. When you made the mod to the antenna to make it tunable, did you change any of the original dimensions or are they the same and you just added the larger tubing?

I think we talked about this the other day and you said when you tuned the antenna low to the Earth it was good at 27.205, but when you raised it up higher the resonance or the good readings showed the antenna drop down in frequency. That could have been another thread I was on where this topic came up.

How many digits read out on the LCD display for SWR? My meter reads two places past the decimal. Yours could read only one digit past the decimal and that compared to the analog meter may differ.
