Anyone do a comparison either sequentially (owned one and then the other) or ideally simultaneously of a well placed 80 meter dipole vs. a 2el long(er) boom Hi-Q coil beam? I currently have a F12 Sig
Same thing applies to a well built 4 sq vs. a 2 el beam. I can't tell you much about one el vs two el, but I can tell you about two el vs 4 square. Back around 2000 I played horse races several times
I have used a rotatable dipole and a beam on 40m and the beam is much better, in my opinion. I would expect the same results on 80m. You can read NQ4I's 80m four square vs. beam comparison in the arc
A couple years back I did a comparison between my 80 four square and 3 L wire beam at 100 ft at the same QTH. On the short DX I couldn't tell the difference, however on the long DX the four square wa
This is a tough comparison since you were much closer to the ocean than W4AN. Same thing applies to a well built 4 sq vs. a 2 el beam. I can't tell you much about one el vs two el, but I can tell you
Hi Gary: For two years I ran the Force 12 EF-180B rotatable dipole at about 100' I switched out to my homebrew 2-el coil loaded Yagi in 2002 and it has been an outstanding DX performer. A direct answ
Steve, Nowhere on your website can I find the MOST important detail of your 80m yagi: HEIGHT ABOVE GROUND. Don N8DE Quoting VE6WZ_Steve <ve6wz@shaw.ca>: ______________________________________________

I have right now on 80 meters 3 element coil loaded Optibeam Yagi at 36m height on rotating tower and also full size 4 Square with 64 ground mounted 1/4wl radials per each tube vertical using Comtek
Interesting.... however using EZNEC and their provided 4 SQ model I see different results then what your suggesting here... a DIPOLE at 136' (what I have) out performs a 4 SQ for all angles down to a
Tonno, Thank you for this excellent objective comparison. Doug I have right now on 80 meters 3 element coil loaded Optibeam Yagi at 36m height on rotating tower and also full size 4 Square with 64 gr
a couple more comments: first off I believe all would agree when you say that the yagi beats the 4 SQ by 3 db to as much as 2 S-units - this is a great deal! Even 3 db as we all know is non-trivial!
EZNEC certainly doesn't model my QTH correctly. For DX, a dipole at 115 feet is interchangeable with a single 1/4 wave vertical in terms of transmitted signal strength. For lower dipoles, the vertica
Hi, Gary. The 4-Square model ("4square" for 40m) that came with my copy of EZNEC has simply a connection to average ground for each vertical ... no radials of any sort. The EZNEC model also shows sta
I think broad generalizations like this are dangerous. I have a 160/80/40 dipole at about 105 ft, and a top-loaded 86 ft vertical for 160 and 80. Which is "better" for any given path will depend STRO
The model included with EZNEC contains no wire losses, no transmission line losses, and no near field ground losses, and assumes average flat ground. Jerry, K4SAV ____________________________________
What I said was not meant to be a generalization. It applies on 80 meters only, at my QTH only, and on short path only, and on transmit only. I thought I made that clear in my posting. FYI, my QTH is
