I still hope for directionality even tho the rotor is at 30 feet but either way it will be interesting unless I move on to another project. I'm sure it will be directive to some degree. But except for receive, what good will that do you if you are 20db-30db down from a dipole due to the excessive inductive losses? I liken your setup to using a MW receiving loopstick as a transmit antenna.. :/ Not a whole heck of a lot of difference except yours is now a massive four shoe boxes in size. Mercy.. It's still puny considering the frequency. My MW receiving loop in this room is bigger than that. "A diamond 44 inches by 44 inches. And my MW loop would almost certainly outdo your design being as it is bigger and uses less turns of coil. "5" It's still a dummy load on a rotating stick... :/ I had to move away from the shoebox size of antenna, what I found out was it worked quite well for receiving but for transmit the eddy currents opposed each other thus preventing particle elevation so the volume is now double what it was but still small enough for the rotor to turn the top band form and light enough to easily put it on the tower So we have validation that your first antenna was a dud when used for transmitting! I'll alert the SPCA! But I'm afraid doubling the size of your dummy load on a stick is not going to pan out in the manner you would like. Even four shoe boxes worth of wound wire maketh not a good 160m antenna. Reboot and try again. |
