Maybe those cables & pipes would radiate some of the signal? Whatever is used to make the signal go far away is fine. It just might be worth a try to see if the ground loop works in the city. Just li

I think the answer to this Roger is "you will have to try it" The ground antenna is dependent on the actual parameters of the ground below you. It can be considered as a vertical loop .....the connec

Hi Mike Yeah, but coupling to 1000 miles of power distribution system would be regarded a cheating by some.......and not really repeatable :-)) Alan G3NYK

Getting a Marconi vertical up in the sky is no mean task when 100m long and carrying a decent antenna current so I was wondering whether there is any merit in using grounded electrode pairs (as used

As with previousl experiments, the trials can be easier than the calculations. Alan -- On Tue, 16/3/10, Roger Lapthorn <[email protected]> wrote: -- http://g3xbm-qrp.blogspot.com/ http://www.g

Im recalling when I was in Antarctica sometime in late 78 and visited (dropped in) Siple station who were conducting VLF experiments using a 21 (42) Kms dipole (2-5Khz and beyond) including triggerin

Years ago it seemed difficult to radiate a good LF signal, that changed when many guys got on the air and figured it out; same with the MF band. This VLF band could be the same way. Get on the air an

Hi Alan, Some would complain that is isn't radio but current carrier communications. Either way if it works, I say go for it...hi hi... I'm waiting to see the day those guys cross the pond on the 8kc
