[Elecraft] Loops

2019-06-04 Thread Peter West
I ran an AlexLoop with my KX-2 from the “no antennas” balcony of a fourth-floor 
apartment for a year while we rebuilt the house and my contest station. Loops 
will work in places where wire antennas are banned or won’t work at all due to 
local noise (like an apartment balcony). Members of our club set up antennas at 
a special event under a concrete overhang at Toronto’s Central Reference 
Library. All the wire antennas heard was noise while the Alexloop got out just 
fine. Having said that the need to retune every few kHz is an issue and CW and 
digital modes are more effective than SSB. I’ve run loops, end-feds, dipoles, 
verticals and beams and the basics apply. In general wire antennas properly 
installed work better. Dipoles work better (quieter and less possible 
interference) than end-feds but end-feds are way easier to get up. If I 
couldn’t get a wire antenna up (I once put a 15-meter dipole up using popsicle 
sticks on the peak of roof of a two-storey linked house that was invisible from 
the ground but set off the smoke detectors if I ran more than 20 watts) I'd 
consider a mobile antenna like a Tarheel with radials and if that wasn’t 
possible I’d run a loop. Let’s put it this way, I’m not selling my Alexloop.

[Elecraft] loops

2004-06-12 Thread Merlarts
I love loops.  They're quiet, have lots of capture area, wide  bandwidth, and 
when big enough, don't have the big horizontal spikes that  collinears or 
other horizontal wire antennas have.  
 
But here's my question:  Does anybody know whether the stup on Radio  Works's 
superloop is open or closed?  Methinks it's probably open, but I  bet 
somebody out there knows for sure.
