When I ran a tower construction company, the crews used to tape over the ends of pipes when they were on top of the truck going to a job site. They said the noise from the wind blowing through them would drive them crazy while going down the road...

It is a dual band 2 meter 70 cm DC grounded unit (as per my specs). I built a mount which offsets the stick a couple feet from the tower. A piece of 1 inch PVC through which I passed a piece of poly rope is attached with stainless hose clamps near the top of the stick to lasso the 17 foot stick to keep it from swaying. A couple times this winter when I was outside, I heard this eerie melodic 4 part tone. It sounded like someone blowing across Pan flutes. Now that spring has sprung, every time the wind blows, there is this tune again. While I questioned my sanity this winter, I do think it is coming from the amateur antenna. Although the sound is somewhat melodic and not objectionable, I fear this summer with windows open in the house, it will keep me up at night. I have this fear it will be like when I first put that tower up and put a 10 foot by 20 foot flag at the top to raise awareness in the community. It snapped so loud it would wake you from a sound sleep. One of my best nights was when that flag finally came down. Since everything was done per my requests, and I want to maintain my stead with the amateur community, how does one keep that stick from making those noises? I am hoping someone here has encountered something similar and has a resolve. Regards, Mike ---------------------------------------------------------------------------- ---- WISPA Wants You!
