Re: Topband: radial wire size

Loads around here too, some still in use. Some laying around on original spools, rusting away. Have pondered hooking up for Beverages. I think I can beat his price :-) 73/Jon AA1K -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Jorge Diez - CX6VM S

I just saw on eBay a 3' piece of barbed wire dated 1878 for sale for $9.78 which comes up to $3.26 per foot! I guess this stuff gets more valuable with age like some good Uruguayan wine.☺ http://www.ebay.com/itm/Vintage-Antique-3-foot-piece-of-Barbed-Wire-Barb-Wire-Barbwire-Bobbed-Old-/1215671

Hi Herb Local price: #17 $16,65 per 100 mts (328ft) #14 $30,32 per 100 mts (328ft) Not problem with thief actually at the farm, but will be very bad if after 2 years the radials "disappear" because of the corrosion 73, Jorge -Mensaje original- De: Topband [mailto:topband-boun...@conte

Re: Topband: radial wire size

In AM broadcast installations the use of buried copper wire (bare) smaller than #10 is considered unacceptable. Here in the Caribbean cooper thieves have found radios stations a good source for black market copper wire and some stations replace thier systems with barbed wire which is harder to

Re: Topband: radial wire size

Hi Jorge, Bill is almost correct, in most soils mechanical durability is the only consideration for long term durability of copper wire, but out of sight out of mind can be a big problem for radial systems in at least two cases. Galvanic corrosion will damage a buried radial system i f smal

Re: Topband: radial wire size

The only real difference when using reasonable-gauge sizes is in physical durability. Electrically it makes little difference since you effectively have a large number of radials in parallel so each one carries only a relatively small percentage of the overall current in the system. I use 18 ga

Topband: DK6ED Double Loop

Hi Guys, Has anyone tried building & using the "DK6ED Double Loop" receiving antenna, as detailed in the March 2015 issue of "QST" magazine...? The rotatable system (i.e. Figure 1, page 35) just looks like a series-connected pair of ultra-miniature K9AY loops, to me... Thoughts / comments...?

Re: Topband: radial wire size

Jorge, It is a mechanical issue only, dependent on wire type. I used PVC coated copper and even thinner than #17. My 130 radials have been in situ for about 15 years. 73 Clive GM3POI -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Jorge Diez - CX6VM

Topband: radial wire size

Hello Thinking in a 4 SQ, buried radials, 60 or more on each vertical What is the difference in performance between installing radial wire size #14 (2.08 mm2) or #17 (1.04 mm2) ? #14 is the size that DXE sell, so I think is a good size for radials. But what about #17? In $$$ is the
