Hi Gary

Thanks for the information.   Have been busy in the garden, but will=

  Hi Dennis,


  Alan G3NYK has an ERP spreadsheet calculator which should be a good=
 estimate & make the calculations easier. Calculators at the bottom of=
 the page & you will find the page here :-

    Hi Luis

    In answer to your question, I calculated using the following web=
 site:
    www.smeter.net/antennas/simple-t-antennas.php and then followed th=
e link to TAntenna which provided a simple Basic program tantenna.exe=
 by A.J.Edwards G4GGQ.   Probably the easiest way is to use a google=
 search for T Antennas and follow the links.

    The outcome is probably inexact as my antenna is really of the unb=
rella type with the tops sloping down, however when I converted from=
 true 'T' to the present setup, no difference was noticed or reported.=
   See attached sketch.

      Hi Dennis,

      A question, please. I am beaconing on 502,25 KHz. My transmitter=
 puts 35 W into a T antenna, high 20 m and an horizontal capacitor top=
 of 10 m.

      With others ham fellows we are discussing what ERP I am sending,=
 but we have no results. Can you tell me how measure or are you calcul=
ating or estimating this ERP?

      Thanks, 73

      Hi Graham

      I tried sending to you 1630-1635 and 1940-1945 local times today=
 Saturday 30 04 2011, but no reply.   I guess you could not hear me,=
 or I you.   I send CW 25watts into a 'T' aerial 20m top and 10m verti=
cal.   Estimated erp 250mW max.   Anyway, I hope you had a good day wi=
th plenty of DX.
