Right now, the FCC is actively seeking input concerning impediments to amateur radio communications. IMO, if there was ever an impediment --especially to weak-signal Topband communications-- it is RF
You don't need 120 radials. The optimum radial length is shown on the chart at http://www.w0btu.com/Optimum_number_of_ground_radials_vs_radial_length.html 73, Mike www.w0btu.com _____________________
Thanks for the wisdom, Rich. :-) However, I've always wondered about the following statement. My question is, on what amateur bands is this common? And on what amateur bands is this possible? 73, Mik
That's exactly what I was thinking. 1000' foot spools of flooded Commscope RG-6 are well under $100 shipped, last time I bought some off eBay. That's what I feed my Beverages with. Having said that,
I'm pretty sure this surface wave at ~0 degrees elevation is useful on (and below) the AM broadcast band (especially the lower portion) and 160 meters. But what about at 3.5, 5, 7, 10, 14, 18, 21, 24
And this seems like a good place and time to ask another question. I get the experience that the usefulness of NVIS radiation peaks around 80 meters. It's not useful on the AM broadcast band, and it'
Multiple Beverages at the same feedpoint? When I put up my Beverages, I avoided doing that because I read at least one bad experience of someone who tried that. (My Beverage feed points are hundreds
I've never operated mobile, but it sounds like you're saying the daytime local range on 160 and 10 is comparable. But Rich is also talking about the radiation at zero degrees bouncing off the ionosph
Let me expand on what I said previously. I always thought that ground wave propagation decreased with frequency. For example, don't AM broadcast stations in the lower end of the AM broadcast band hav
I don't think the length is the reason that you're not hearing any signals or noise in the reverse direction. How well does it work on 40 in the forward direction? I don't know all the details of wha
Is this the Beverage above the fence that you mean, Greg? http://www.g3xrj.com/RxArray_files/2wire_bev/2wire_bev.htm That was a good article. 73, Mike www.w0btu.com __________________________________
Herb, Very common problem, with a simple solution. Ants are attracted to the magnetic field around energized wires. Turn off the power to your Beverages whenever you're not using them, and I'll bet t
There's just one possible issue about all this that is conspicuous by its absence, as they say. At least in some installations, having feedlines going to each end of the Beverage supports is going to
I'd be interested in looking inside one, too, but exactly what IS their price for everything you need? I see a bunch of separate components on their web site, but no system package containing it all.
Well, I have a good reason for asking. I may very well offer a complete bi-directional Beverage antenna system for sale someday. (And I gar-ran-tee you that no ants, etc. will be able to get inside.

Sounds like fishing net beacons, Joe. http://www.genesisradio.com.au/VK2DX/fishnet.html http://www.w8ji.com/ndb%20beacon%20fish%20buoy%20net%20beacons.htm 73, Mike www.w0btu.com _____________________
Hi Joe, There was quite a bit of discussion about fishnet beacons here a year or two ago. If you search back through the Topband archives, you might find your answer. http://lists.contesting.com/arch
Those blasted illegal fishnet buoy transmitters are in use all over the world. I haven't spent much time on 160 in over a year, and I almost forgot about them till you mentioned them. I could usually
Here's the page that I regularly look at to determine whether I want to go listen on 160 or 80: http://www.intellicast.com/Storm/Severe/Lightning.aspx And if I want to know if a specific DX location
