There used to be such a "farm" owned by Collins/TI (Don't remember) east of highway 75 north of Dallas...very large open space with a number of different types of antennas. The only place I ever saw a log-periodic HF multielement beam!
There'ya go, more than you ever wanted to know...
Standard TV antenna tripod, un-guyed, just wood screws, sealed w/liquid tape. Small enuf it has very low wind loading.I might just take you up on that invite when I get back from the summer trip and begin to re-situate my End-Fed PAR and add the loop. Making the wire longer and see if that helps. Also, how do you have your tripod secured to the roof?
No need for dipoles for receive-only. Dipoles on SWL have always limited my results around their approximate length - plus or minus 50% or so. Even with open-wire feed. For example, my 66-foot dipole is OK for about 4 to 11MHz. A 100' long wire at the same height will work beautifully across the entire HF (and MW) spectrum.Need good recommendations for an HF receive antenna. Already have the end-fed PAR 40-ft wire to my Icom R75 and R8600, but when I recently went to a few online SDRs and did some comparing, I found I was seriously lacking good signal reception. I am thinking I need a longer and better wire. I am partial to dipoles, but feel free to steer me to something new if you want, I am open to suggestions. I do mostly utility monitoring, milair, amateur radio, and some international and domestic shortwave broadcast. Taking my General class test here soon, and I already have a pair of trip beams scoped out that I plan to purchase the day I pass my test. I have plans to upgrade from a 746Pro to something bigger and better. But, right now, I am just in the market for a good HF RX antenna. I have about 125 ft of space from my antenna mast to a tree in my backyard. I also have space on my mast. Thanks in advance for all of your suggestions. I truly value the technical information here and the opinions and suggestions from people who know their stuff. So, fire away
I have this loop bookmarked to get when I get back home at the end of the summer. Maybe I have some more reading & research to do on loops. Thanks for the input.As for the W6LVP loop, I heard both the Pixel and Wellbrook are better, especially for permanent situations. Looks too flimsy after my friend bought one and returned it. Looked too weak compared to the other 2 loops. Not only that but there was not enough amp in the receive side. Again...YMMV
Don't make the mistake of comparing the loop to a wire antenna - they're not the same animal and work very differently. I think you'll find that the advantage of being able to null out noise (and on MW and LW, interfering signals) is going to be your big plus
Put another way, don't compare signal strength between the 2 - loops simply don't work that way. Rather look at the quality of the signal - is there less noise, fading, more stable - and evaluate it that way. Sure propagation isn't going to be kind to us for several years to come, and there may be times when the signal is better on the wire. But propagation, like luck, is a very fickle thing - one day the wire is better, the next the loop might be.
The LVP loops have a great reputation - I want to get the kit when I get my SDRPlay this fall...enjoy...Mike
