Should I run a Sky-wire loop?
Walter, Give the Skywire loop a try....I put one up almost a year ago and it definitely is better than my other wire antenna ( a 40m dipole). Mine is approx 440' long and is shaped more like a rectangle than a perfect round (or square) loop. Each corner is at a different elevation, the higest 35' , the lowest 20'. I feed it with RG8X, no balun, and my K2's autotuner permits effective operation on all HF bands at less than 2-1 SWR, except on 160 where it only tunes down to 3.5 to 1. I haven't done it yet but I've worked out a way to enlarge it another 100', so the 160m swr should come down. I also plan to try switching to 450 ohm ladder line feed.....everyone says it will work even better. Did I mention it is the "quietest' recieving antenna I've used?.... But don't limit its use to only recieving....the horizontal loop is a great transmitting antenna too. My first contact with mine was on 20m to Tierra del Fuego at the southern tip of Argentina ( 5 watts ssb, got a 5x5 sig report!). Seems to be somewhat omni directional too as I've worked dx in all directions. I don't claim it will outperform a good beam on a tower but the price is right (cheap) and its realatively easy to make. Go for it! Regards, Rich K2CPE |
