I suggest you use coax with a stranded inner conductor for the rotor loop. I believe Times LMR400 has a solid core. RG213 typically has a stranded core but the PE dielectric tends to be on the stiff
compatible with HDX and MA series towers. 73 Matt KM5VI Will a TX2 fit in the top section of a UST HDX-589 tower. Seems like I had one years ago but can't remember. Julio, W4HY _____________________
Jim is correct. Years ago when I had Beverage antennas up for low band work, I found them quite effective on 20M for cutting higher angle stateside QRM. 73 Matt KM5VI Before I had aluminum for 20-10,
4 switch conductors are required for running a reversing induction motor at 120VAC. There are drum type switches available as well as motor rated 3-position 3PDT toggle switches (9 terminals), or you
Hi John & Rick, Thanks to you both for making much useful information available over the years - which I have used on many occasions. I used the term fractional loosely - slang for small single phase
When the surface area of the anode is relatively large compared to the cathode, galvanic corrosion is generally not a problem when the stainless is cathodic. Hence using relatively small 18-8 stainle
Good point Jim, I can back you up on the phosphor bronze as a dielectric as it does work very well. Regarding avoiding the SS hardware path, I have lately been using AL or CU straps cut from a sheet
Just Google limit switches and a multitude of suppliers should show up. The Honeywell and Omron are a couple of popular manufacturers. Going rate is about $35 each. Look for switches rated NEMA 4 for
Look for 18-8 or 300 series stainless steel. The 18 means 18% chromium and the 8 means 8% nickel. 73 Matt KM5VI From: Raymond Benny [mailto:rayn6vr@gmail.com] Sent: Sunday, March 03, 2019 11:07 AM To
YW results for modifying Hy-Gain monobanders have been spot on in my experience. Beware of a few things... (1) adjust your build dimensions for your boom tubing radius - or - add a dummy segment to y
I had some significant damage to some of my antennas a few years ago resulting from cattle running into them. Even a robust vertical won't hold up to a 1200 lb steer. I did not suffer any radial dama
I have several graphite molds, but I did not know about ceramic molds. It's important to treat the graphite molds careful because the graphite damages easily if abused. I am told they will eventually
Steve's criteria is sage & valid. Know what to look for in assessing wire rope condition. Suggestions if you are building your own cable assys... - Buy US or reputable mfg. wire rope. Avoid the Chine
Hi Art, I'm sure you will get many responses, but considering your situation, here's some ideas: Option 1: Rent a boom fork lift truck (such as a Lull or a Terex) from your local equipment rental com
Since this thread has somewhat morphed into a series of entertaining RFI stories, I thought I would chime in... Many years ago, my newlywed wife and I rented a home in an older West Houston neighborh
You might want to check the website of NR5M. I believe he has a broadside array of 4-squares. Good luck on your project. 73 Matt KM5VI _______________________________________________ ________________
I acquired several sets of Daniels "Military Style" open frame crimpers with an assortment of interchangeable dies several years ago... best thing since sliced bread! I believe these are also markete
Hi John, Some random thought for your consideration: 1. What is your intended use - DX? Contesting? General Ragchew? Based on the number of times you call shows up in my contest log I'll guess it's c
Hi Mike, I believe the wires are color coded as follows: Pin 1 Black (heavy gauge) = ground Pin 2 White (heavy gauge) = brake Pin 3 Green = azimuth feedback reference (potentiometer CCW side) Pin 4 B
