New UHF Spectrum antennas?

Hello,
I was hoping someone (Holl_ands? or Niklm) would post some antenna designs rescaled for the new UHF spectrum,
but I haven't seem any here.
Anyone know if Holl_ands is still active on this site?
I would really love to build a Fat Dipole antenna for the new UHF spectrum, I have lots of tubing lying around waiting to be used!

Hi Schoolbus

Here's a design for a UHF antenna made from 1/2" copper tubing, soldered joints and a 1/4" bolt to separate the element from the reflector. Feed point is made by soldering in #10 copper screws, through holes in the copper elbow. I designed it to work well from 470mhz to 700mhz. Many of the parts are sized to make the antenna easy to build. Tubing lengths are sized so that they are cut to the nearest 1/2". Lengths in the NEC file are for the tubing and the joints, so lenghts might be effected by the brand of elbows and tees that you use. I've got a version that is made of 10 pieces of tubing cut 5" long, and 10 pieces cut to 8" that is almost as efficient. The design could be optimized a bit more, if you weren't concerned with keeping dimension easy to measure and cut. NEC file below.

Hello,
thx, my tubing is all 1 inch, which is why I was hoping to see a revised Fat Dipole antenna

I don't have any personal information on the question, but the forum shows his "Last Activity: 2019-10-17 01:17 PM".

Holl_ands has posted some new spectrum designs on his imageevent page, but not the fat dipole. There was also a recent thread about a new spectrum GH antenna, but again, not fat dipole.

One could also use the scaling calculator at: Martin E. Meserve - K7MEM - Antenna Frequency/Diameter/Length Scaling to scale an older fat dipole design for use on the new spectrum. It would not be optimized, but it should be close enough.

The last activity by holl_ands on the other forum he uses, AVS, was on Oct 5, 2019. So, it's been almost two months since he was here on DHC, which is unusual. I wonder what happened to him? He is an expert antenna modeler.

If you can not measure it, you can not improve it.

What type of antenna did you want to make for UHF, a yagi or something like a 4-bay panel antenna like the M4 with fat tubing elements instead of whiskers? The 4-bay would have wider bandwidth than the yagi to cover 14-36 on UHF with more constant gain across the band. It would be similar to the Winegard HD-4400, but use tubing instead of wide strips.



https://imageevent.com/holl_ands/mul...winegardhd4400

You would need to increase the element lengths and vertical bay spacing for 14-36.

Something like this 8-bay fat dipole is what comes to my mind. I have used it as a basis for scaling to fit the tube I have on hand and the channel I want to receive, but never got around to actually building.

Don't know what Holl_ands has been up to the last couple of months, but do remember reading that he has been teaching a grandson to run the antenna modeling software. Been wondering when/if we might hear from the grandson...

Neil, that 8 Bay Fat Dipole is what I am after, but scaled for the new UHF Spectrum.
I have a LOT of 1 inch stainsteel tubing!

Rabbit, the HD4400 antenna is in the same zone- but from what Holland modelled of those Wineguard antennas, they seem hi gain but very narrow focus. Which is why I like Hollands Fat Dipole Antennas, they are hi gain, but wider focus, which is what I need where I am located (Oshawa Ontario, trying to pick up but Toronto and Buffalo and Hamilton)

IF only Holland could redo his Fat Dipole antennas scaled for the new UHF Spectrum.

The Dipole Antennas, do much better on the lower end of the UHF spectrum than the M4 style antennas, which is why I want to build one of those.

@schoolbus ,
Its quite simple to frequency scale any antenna from a higher freq to a lower freq.

Just increase all dimensions, including the wire radius by a frequency scale factor of old_freq/new_freq. A quick and dirty method would be to modify the existing model's scaling card (GS). For example in holl_ands 8 bay fat dipole, UHF Vert 8-Bay Dipole + 43 Pair RR - OPT
try changing this line. And see what ya come up with.

Code:
 from
GS 0 0 0.0254' CONVERT ABOVE FROM INCHES TO METERS FOR NEC.
Code:
to
GS 0 0 0.028275' CONVERT ABOVE FROM INCHES TO METERS FOR NEC.
In other words from .0254, to .0254 * 590 MHz/530 MHz (chosen rather arbitrarily looking at the existing model's freq sweep).
resulted in a very similar pattern, that rolls off much sooner and 15 dBi gain at 470 MHz, instead of 13.5 dBi gain in the original model.
The peak gain essentially unchanged, 16.75 dBi but occurred at 614 MHz, instead of 680 MHz. Without any further optimization.

Though the dipoles would be like an inch O.D., phasing lines like 1/8" O.D. and the reflectors like 3/8" O.D.
And around 67" tall...

That doesnt sound bad.
Would the lobe pattern be the same?
Could I do fencing instead of the RRods?

here, in this quick hack, I multiplied all holl_ands' symbols that are used as inputs
by 590 MHz / 530 MHz.

Lawrence, Very good antenna info, thanks for the NEC file!!

The design modified to work of 470mhz to 614mhz made of 1" tubing.
The Lengths in the file of MmanaGal are in meter
