Continue to use the radials on top of the roof... Install the mesh
under the roof (attic I assume) and lap it over the rafters and just twist the free ends to each other so that the mesh is relatively one piece... Don't bother with solder.. Don't waste your time connecting the radials to the mesh... The radials will couple with the mesh electromagnetically... If you are planning on putting the mesh out on the roof ( I would not because it will rust and disintegrate in just a few years.) It has to go underneath the radials, not over them... Again, do not mechanically connect the radials to the steel... Just the proximity will couple them... Think twice about putting the mesh outside... You will have a nasty mess very soon... denny / k8do |

As far as I can judge the ceilings have about a foot of insulation and beams above then (probably) timber and is covered in several layers of heavy duty bitumen based roofing material. The mesh will have to go on top as I think the XYL would complain if I stapled it to the lounge ceiling. The chicken wire will have a secondary function of deterring the large number of seagulls that plague the town (Dover) :-) Dick G4BBH |

Dick, the usual galvanised, chicken wire available in the USA is good
for 3 seasons near the ocean, tops... Then they turn into rust balls... Unless your chicken farmers there near the coast have better materials available I would be wary... The gulls that hang around my boat will stand on anything, I doubt that chicken wire would bother them... I also doubt that putting the mesh on the roof will make a major improvement in signal strength, especially if it is above the radials... First your radials are already elevated above the ground a significant fraction of a wave which reduces ground losses... Putting your money/energy into having 6 or 8 quarter wave radials for each band is more likely to show a better result... cheers ... denny / k8do |
