Hi all, Taking up the thread of the ERP discussion, and consideration of verticals or a dipole: At the rather long wavelengths of interest, amateur antennas at LF are usually very short in electrical
[...] If sky wave mode is what is actually being sought after, then it may well be worth experimenting with a horizontal "dipole"? assuming the above hypothesis is valid, why not a horizontal loop,
assuming the above hypothesis is valid, why not a horizontal loop, which could be much smaller than a dipole ?Andre' N4ICK I was not meaning to restrict the idea to a dipole, but rather to stimulate

Hello, [...] I might have acces to a 800m (0.36 lambda) abandoned telephone line, but the wire will be only about 6 meter above ground. Will this work or will I only get in the Guinnessbook of record
Driven as dipole over "average" ground it will be a nice cloudburner with -10 dBi. At 5° elevation you will get -31 / -16 dBi ("8-pattern"). Feed point impedance will be approx. 5.5-j500 Ohms. Anyon
Any idea how high (above ground) the antenna of ZL1WB is ? I might have acces to a 800m (0.36 lambda) abandoned telephone line, but the wire will be only about 6 meter above ground. Will this work or
Dear all, The important thing about any LF antenna is to ensure that the wire is supported by good insulators, nothing kills the Q of a system like a wire touching a damp tree or similar lossy struct
Hallo lieber Rik, und wie würde das Gebilde funktionieren wenn es endgespeist wäre ? Dan müste ich die Telefonleitung nicht in der Mitte unterbrechen. Ja, dass scheint kein Problem zu sein. Allerding
