Hello all,
the recent discussions on loop antennas inspired me (at last) to start with
the loop antenna section of my "antennas for 136kHz" webpage
(http://www.qsl.net/on7yd/136ant.htm)
I already have some basic information about loop (as transmitting antenna)
but I'm still looking for more info.
In particular I am looking for :
1. practical results with loops as transmitting antenna
- measured loss resistance (eventual loop-current vs RF power) related to
the loop dimensions and used wire
- other details on loops that were 'real world' tested (dimensions,
eventual drawing etc...)
- matching loop antennas
- tips for contructing loop antennas (do's and dont's)
2. efficiency of loop antennas
- how to calculate the radiation resistance
- overview of expected losses : copper-loss, ground-loss (edison effect ?),
proximity effect etc...
Of course any other information about transmitting loops is most welcome. I
assume that short info can be sent via the reflector, longer mails and
mails including attachments should be sent direct to me ([email protected]).
73 and many thanks in advance,
Rik ON7YD
