It depends. Electrically you will be fine unless you're using a published design that used through-the-boom elements, in which case there might need to be adjustments. Physically it will depend on m

Another vote for Thunderbird. I switched to it when Eudora went away. Wes N7WS For many years, I've used Thunderbird as an email client, and before that, a similar program carried over from OS/2. B

W8JI.com I have a full quarter wave vertical made from Rohn 45. It has the broadcast tower insulator section 27 feet above ground and I use 1/8th wave radials with an inductor for tuning to resonance

Since you don't want to read any manuals, this is probably a moot point, but the VNWA software has TDR provisions. Whether you can get enough data out of the FA-VA5 or not isn't clear to me without

Another thought. I'm a little short of space between the vertical part of my L and the tower which supports the far end of the loading wire. So I feature it; the feedpoint is capacitive and below 50

I would bite the bullet and put in some hardline. Messing with OWL and baluns/transformers, etc. will be nothing but grief. Wes N7WS On 5/16/2022 3:39 PM, dave arruzza via TowerTalk wrote: To all..
True open line with wide spacing and sparse insulators will likely not be affected too much. But weatherproofing the transformers, etc might be an issue. Probably not where I live where we've had 0
