Re: LF: Loops v Verticals
broadcasters want omni coverage so a loop
really wouldnt work in this application
Not true. Broadcast stns located
in coastal areas do not waste energy beaming out to sea. Likewise the
old marine coastal stations working ships at sea tried to direct the RF
seawards and not inland.
I never did see any LOOP antennas
at these installations.
Loops do have the disadvantage of
being bi-directional and not what a radio amateur wants. On LF we want
coverage in all directions.
however for Amateur work they would appear to work
quite well,, The proof is in the pudding where a TX at
1 watt input provides good coverage,,, if it weren't for TX
folk with small lots and shade trees ,,,LF activity would
But verticals do work after a fashion
For those that do not know.
Research around Europe has shown that VERTICALS are the only antennas
suitable for Transmitting on LF. Loops are fine for Receiving, little
or large but the bigger the better. Who has ever heard of a LF
broadcasting station using loops for TX.
