Actually I did one better... I found a great power point presentation and read that whole thing... Really dug being able to see the SWR plot that you had in there and that gave me a lot more confidence that I was going to be able to use my internal ATU in the K3 to get enough swing to get the job done. I'm not expecting to get much of anything below 40. I may try it but only to collect some information and write up what I find and store it away for the well in a pinch that can kinda work or don't even try... I do plan on building something similar to what you'd shown for doing 160 and 80 just to say I've built one and to make the setup that much more versatile should the need arise to get on the low bands.
Looking forward to setting it up and collecting information then getting to do some comparisons between the 43 ft vertical and the Carolina windom which I'll be using together for diversity. Then I'll have one other wire up for RX only... I love having options! ;) My home station is such a compromise that the compromise situation that I get to play with on FD is just a pure joy! Not to mention that new locations also make it fun and interesting. Thanks much for all your information on the 43 ft vertical! I've found it quite informative and it gives me good information to go on to make sure things are coming out how I want. The plan is to feed it w/ 100 ft of LMR 400 or 50 ft of 9913 depending on how far away we have to put it and which gives us the best results if both are an option. ~Brett (N7MG) On Wed, Jun 23, 2010 at 9:43 AM, Phil & Debbie Salas <dpsa...@tx.rr.com> wrote: > "...Ditch the 43 foot vertical!
