Gain Master vs Antron99 proof at last !
- Thread starter RadioDaze
- Start date
I'll stick with my starduster. it's like broadcasting from the moon which gets me much farther up than both of those antennae.
Worthless post. Neither the photo or the link worked for me. But i really wouldn't run either one of them, so who cares??

The 2 guys who post above you did not seem to think so. It is a joke and I think it must be your internet that has a problem as it works here just fine.
I enjoy visualizing how radio waves are propagated and just extended it into a mickey take of the never ending xxxxx vs xxxxx antenna debate . (I cannot quite believe I am explaining it)
Ok nothing to see here, move on..........
We had something that looked like that Starduster called a Thunderpole III in the UK
Remember it had a helically wound coil... just for extra losses.

Cool depiction of the lower TOA of the GainMaster, all things being equal. I must be missing the joke.
So I'm curious, what forum did this depiction come from?

Hmmm, I must be missing something. Looks like the GM is further from the RX station than is the A99 and yet they both appear to be having similar success due to the lower TOA of the GM.
I guess the A99 TOA is over my head...
Anyone on that island in the middle of the picture won't be able to hear either of them without a really tall tower.

Ya see...those two lines in space above the earth are meaningless. I can go into Photoshop and change the gain master label to read "57 Chevy" to prove the 57 Chevy has a lower toa than the Antron
Ha yes I just made the depiction myself and drew the lines on.. the joke is missed because I missed "Scientific verification" from the thread title I guess... irony/sarcastic.
Too sensitive a topic to joke about maybe. Fact is it all depends on where the RX station is and of course the random and chance ionization of specific areas of 2 layers of interest to us... the E or F and where your antenna so happens to be putting some energy.
I do enjoy using my Gain Master but have had very long DX using a 1/2 wave basic Silver Rod ($45 vertical about £30) as well so ultimately a lot of guess work involved in 1 antenna being better than another. I get a little further with the GM on the line of sight and ground wave contacts and the antenna is a dream to set up perfect SWR all over the band every time. No fiddling about and you know all your juice is getting put out into the ether.
I think the 1/2 wave might have the edge on the short hop Sporadic E contacts. So hard to quantify though as that E layer is charging and discharging/switching polarization so fast there is no continuity over time.

Well....figure of speech... only technically correct at very low frequencies MW etc.
What I mean is point to point (as close to ground as you can get) and not via any atmospheric layers.
Conversely and something to think about...
If there is no ground wave component why does the signal diminish in strength? If it just going through space/air/ether above ground level we should be able to pick it up no problem.
Here is something I quote from a recent conversation with someone:"1000ft the optical line of sight is about 38miles so times that by 1.3 for radio waves because of the slight bending affect of the atmosphere on ground wave signals, say 49.5 miles so two stations each at 1000ft would have a line of sight of nearly 100miles"
Given this why do I regularly speak 100miles from a height of approx 450ft with the RX end being not much higher than myself of lower. Happens every week I am out on this hill virtually, different contacts. My "local" chat is 70miles + with ease.
I spoke to someone with the Gain master 120 miles away one evening this week when the band was very, very dead. I spoke to them twice, an hour in between QSO's at Signal 0 both ways, same audio quality on both QSO's. He was at 240ft ASL (using a mag mount mobile antenna) and I was at 350ft ASL. Technically that should not be possible line of sight, well over the horizon by a factor of 4.
Is it a ground wave component ?

I'm sorry, I guess I was on the wrong page
I thought that was a 'Clever depiction' of what to expect from a lower TOA antenna, showing it utilizing the ionosphere from a greater distance thus allowing contact from a further distance.
You meant it as a joke, showing photographic results of a filmed-while-testing photograph, now THAT'S funny
why not just power up a klystron 2kw get some waveguide hook up to that unused dish and bounce off the troposphere, see how that range does hmmm maybe and I mean maybe 750 miles hmmm might squeeze 1000 miles out.
