I got so disgusted with the uselessness of my 259B that I dumped it on Ebay. Back to the old faithful Birds with my son in the shack driving a cable with an exact 10W on 440 MHz when I signal him. Th

You didnt say how tall that tower will be. Many 6M openings are high angle so you might consider mounting the loop down low in the 20-30' range on a side arm bracket. Or mount it on a mast attached t

At one sun peak I had a hard time running JA's with a 4 stack starting at 30' that could be selected as upper pair, lower pair and all four. Put a single fixed antenna at 20' and ran them for hours.

If you redid that sequence without the flowery backround and better camera focus I might be able to view it. All it does now is make my eyes water! Give an old man a break. Carl KM1H Great point Stev

Several published tests show a good PL-259 coming to almost a perfect 50 Ohms at 222 MHz but exhibiting a bit under 2:1 at 432. While that VSWR wont bother a FM wanker or scanner its not good at QRO

2" at 432 MHz is almost .1 wavelength and becomes an impedence transformer as you already mentioned. If it is at the antenna end you would need a Smith chart or an asymetrical impedence transformer f

If the exercise is simply to find that particular length then calculate at what frequency it is a 1/4 wave using the published velocity factor. Cut it a few percent longer. Then short one end and con

You can buy hardware in bulk at a fastener company, most of which have a walk in counter; a lot cheaper than a hardware store. Grade 8 is the best unless you want to get into mil-spec grades. Carl KM

That is a blanket statement that doesnt hold much water. Belrose and others have published also and believe that 12' is adequate on 160 in many cases. BC band engineers have proven that an elevated s

A tree can be effective as an antenna also. It all depends upon what level of efficiency you are happy with. What you are talking about is called a ground plane and has been around since the 30's. Th
