What about a K9AY RX antenna if limited room (or flagg or pennant), or a beverage is room is not an issue? Or you can also use a small receiving loop . I have used the RX loop, and want to build a K9
Have some one you know take a hardness on it. If it is soft, then it would show up quickly. More than likely it is a heat treatable grade, or possibly cold extruded 5XXX. I have been looking for a so
The 25GSSB base is 1/2" thick, while the BPC25G is on the order of 1/4" thick. That should help understand the difference. --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertal
Run a simple model - then look at the patterns. That should help you decide. As an alternative, you can look at using a quad. As I recall, it performs as well, or nearly so, as a 3 element Yagi. It a
The Zero Beaters ARC in Washington MO will be having there FD at Lat 38.399°, Long -90.9363°, with 80M full size loop at 50 feet, and TH6DXX at 60 feet on a portable tower. Should be a fun time. I wi
Honesty in an owner is always appreciated. We have all made those types of mistakes. Thank you for letting us know. Good Luck Scott, KB0FHP Greetings all, This is Rob, W7GH from Idiom Press. I took o
Depending where he is - I would recommend the K1FO D505S - very modest and equal performance to 6M5X, but built a bit better for the northeast. Try Directivesystems.com Scott --Original Message-- Fro
I have a a couple of old rotors - a TR4 and TR44 each series 330 and 568. Are these of any use or should I throw them away? I also have a series of control boxes. I do not know which goes to which. I
One month is too short a time. Give him at least 3 months to turn things around. Scott Has anyone noticed an improvement with this company since Rob's email of July 3, 2008? Comments posted on eham a
Think of it as something preventing from over turning. Deeper is always better - you have more resistance from the soil reacting to the moment of overturning. The force would be the same, but the mom
Simple to use and reasonably accurate - and free is MMANA Hello, I have been considering various antenna design/analysis programs, such as the Teri software program. I would like the groups opinions
Is that true? What about the series I and Series II rotors? Didn't they have a slightly different wiring? --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contest
I have a small yard - a very small yard. I use an 80M loop and it takes up 3/4 of my yard. Needless to say, I do not have space for 120 radials 100 feet long. I have height - a lot of tall trees. My
I will try that...tying the ends together. As it stands now, connecting the loop to the tuner in normal fashion, I am able to get a 3:1 match. So there is hope. I also use a 80M vertical with a capac
Dan: Do you have any issues with interaction or funky pattern distortion that close to your flag? Scott Scott, I have a small yard too and I do fine on 160/80 with 100W. My radials are #18 stranded b
I like that idea. I was concerned that I would have issues with changing the loop. I really like the loop, especially for working local contacts. It works very well for 80M and 40M on Sweepstakes. Th
The location of my tallest tree is "just on" my property line. The property slopes strongly front to back. Because of the location of the antenna, to obtain a symmetrical field, I would have to go in
Felipe: I use an 80M loop horizontally. I feed it with 450 ohm ladder line. I have also used this configuration numerous times in the past. I have not had a problem feeding it on 80M if I used a 1/4
In the ARRL Handbook, 8th edition, Chapter 10, pages 10-12, describes just such an antenna. I built one for Field Day and it worked extremely well. It was nice to be able to rotate it around by movin
As with all things - there is a lot of myth, mis-information and fallacy about heat treating. Since I do this for a living I might as well join the fray. 6061 and 6063 are hardenable, heat treatable
