Sounds like the original Hy-Gain Long John for 6m. Excellent antenna. Hopefully, someone has a manual for one laying around. I don't think they are in production any longer, but you could take a look

Hi Tom. Your radial/ground loss measurements were repeatedly referenced in John Devoldere's book, so I thought I would point a question your way (and the way of any other TowerTalkians who might wish
Tom, you were correct about the rising Z. Thanks so much. I found out why the input Z was going up as I put more radials in...I was measuring at the end of 55' of LMR-400 (as opposed to the measureme
I was copying them S-6 with an S2 noise level Sunday morning on 80m ssb. Using an inverted L (45 x 25') with 26 radials. I didn't try to work them because the pileup was too thick and I had little ti
I'm having great success with my 80m inverted L (45' up and 25 or so feet out), with 26 radials (now). (Hung off the side of my tower) I had a thought for something to just "get me on" 160. Is there
When I have used and modeled this antenna I found that the wire is not such much a radial, as a "slant wire feed" for the tower. The tower/beam/etc are in fact doing the radiating and the wire is jus
Alan, The double bazooka (as conventionally described) is a waste of "weight". It will not outperform an ordinary dipole in terms of gain (it has extra loss, which is where the minor VSWR bandwidth i
Jim, The "fan" dipole, and the bow tie are examples of broadbanding without loss, assuming you are talking about the two wires being resonant on the same band. I've seen a fan dipole with one wire cu
I also used a T-10 for years at 72' and it was an outstanding performer. When I moved to a new qth with a much less capable tower, I dropped to a T-6 and have been surprised how well it works. I'm a
No, larger wire only helps from a strength/breakage/corrosion point of view. You say you have 1000' of radials, but didn't indicate how many. As long as you have enough of them, the wire size is imma
But....aluminum in a lot of soil types will disintegrate in a couple of years, so best to know the soil characteristics before making the effort to lay a bunch of aluminum down. 68 bucks for a 1000'
If you are talking about elevated radials, they have to be tuned for each band at a 1/4 wave. At the very minimum you need two for each band (on opposite sides of the "circle"). The higher you get th
Actually, they can be MUCH shorter than .22 wl, as long as you have enough of them. Many more shorter is quite a bit better than many fewer longer. There are free programs by G4FGQ, RADIAL2 is the na
Bill, If you don't understand the fascination, then you are not a DX chaser on those bands, in which case you have no use for a vertical (other than convenience or quick temp setup) If you seriously
Yes, that is a "special case" and has been theorized about in the literature...however, the general and more typical case is low angle based. Asserting the exception doesn't create the rule, it just
Dave, If you are going to lay the radials on the ground and the vertical is ground mounted, then I think you would be very happy with the moderate performance of 16 radials, 1/4 wave or so on the low
Dave, Do a neat trick with your antenna analyzer if it shows impedance: Before you put ANY radials down, measure the Z at the antenna (at it's resonant freq). Then put your 8 radials down, and remeas
Hi Eugene, My comments are interspersed in your posting. I run an inverted L for 80m with full radial field and I LOVE the DX Engineering radial plate...first rate, stainless steel hardware...very ni
Hmmm..another variation on the question. It seems one ought to be able to run two inverted L's from the same feedline, using the same radial field (common radial plate). Fanning them out from the bas
