Hi MF
 
Interesting conditions to Reunion l= ast=20 night
 
A total of 23 spots from FR5ZX. Onl= y four stations=20 reported
 
1 from G8HUH at -30
3 from SV8CS best -24=
6 from DK7FC best -24=
13 from EA5DOM best -19
 
=46rom Rick Strobbe ON7YD reference= site for LF antennas=20 I have seen his calculations for a vertical
antenna with inductive topload. May= be is the closer=20 configuration to what I have managed to get here
 
 
There is no mention to the feeding p= oint for such=20 antenna. In my setup H(L) is 80m and I'm feeding
at the coil base. Total H is 80+11=3D= =20 91m
 
The Ra calculated from Rick formula= s is over 8 Ohm (not=20 mOhm)
This radiation resistance seems too= much to be true.=20 But results are proving really outstanding
 
I'm just feeding the antenna with 7= 0W, believe it or=20 not and it is not really resonanting on WPSR frequency but on=20 488KHz
as I adjust the variometer up at th= e antenna and then=20 run a coax line to shack which changes it all
 
The 80m pipe which forms the H(L) i= s really more=20 complex in practice. It goes down to building basement
and there splits into different pip= es. One connects to=20 presure compressor and water tank. The other runs
underground 40m to the twin tower a= nd then runs up=20 again another 80m into the twin (parallel) tower
The pipe section running undergroun= d is not metal, but=20 plastic. The iner water column should work as
current conductor. That water is co= nfined in the pipes=20 and presurized. Should be saturated with metal oxide
similar to a heating circuit, so pr= obably the plastic=20 pipe got metal deposits inside which make it even better
=
conductor than the water colum=20 itself
 
Any thoughts ?? Am I getting >10= % efficiency=20 ??

Hi Genosse Roman,

FR5ZX is using a resonated vertical ant= enna=20 with capacitive top load near his house. He also transmits with this=20 antenna.
