Wellbrook ALA 100 with Rotator - Construction Details
I did mention the spiral configuration to him, but he didn't comment on it.
The construction seemed to be easier, so it's the only style I considered from the start. Guy wrote in message ups.com... Ah, so your loops are concentric. I ran my parallel. Did you discuss this with Andy? |

Spiral concentric or coil will change the pattern but since the antenna is so electrically small it won't make much difference unless you want to use the nulls. I would expect that a coil wound would be best. I you are concerned about using a null in the antenna pattern then go one turn. -- Telamon Ventura, California |
