If the mast is glass fibre and the coax fed at 90 degrees for a wavelength then it has no choice but to be decoupled simply because there is no conductive material to form a capacitive coupling with.

I see that you have modeled a Starduster and not a standard quarter wave. Some strange shit going on there. Firstly if I have read it correctly, the decoupled antenna is one dbi of gain behind the standard model. I take it that Eznec has decided that the Starduster is transmitting on the mast...

Marconi, it would be interesting to see two different models with this Eznec of yours. The first model a standard quarter wave mounted at a tip height of 50 feet and the second a quarter wave mounted at 50 feet to the tip but this time mounted on a glass fiber mast and the coax fed horizontally...

There is no doubt that the half wave dipole works pretty well mounted high and away from the mounting pole, horizontally fed with a 2:1 balun to match the 75ohm impedance. The quarter wave would have a better potential if it can be decoupled from the mounting pole capacitively. Obviously the...

Marconi, you didn't read my earlier post about tip height I see. Nav2010 wrote

I was referring to the Marconi 'Eznec can cook a fried egg on its own' brigade as an whole.:pop:

I've had the tips at the same height as an half and 5/8ths wave and i've had them ever higher than a 5/8ths wave, still not as good. I have a mast that is on a winch system and I could get an antenna on and off within 30 minutes and set the height where ever I like. I have good friends all over...

Here is my list of best performing antennae including modded versions. 1. Open sleeve types (Vector, siggy4 etc) 2. 5/8ths with full quarter wave radials (i10k, Mr coily etc) 3. 5/8ths/.64 wave dipole (Gainmaster) 4. 5/8th wave with radial kits or shorter radials (Sirio 827, Imax with GP...

I don't care if the Queen of England wrote the software and Isaac Newton designed the quarter wave, it ain't as good as a 5/8ths wave. My mind isn't closed, I've had 2 quarter waves up on my pole and they are on a par with a half wave or maybe just under, my tests were done on the same coax...

Eddie, my experience is that a 5/8ths wave performs better than a 1/4 wave GP, this is my real world experience. I don't care whether Eznec says a quarter wave can work wonders and shit cucumbers it will not change that fact. No matter how much you twiddle and manipulate Eznec to say otherwise...

Houses ,terrain, coax, relative soldering skills and any other real world interferences are what's irrelevant to simple antenna comparisons. So if Marconi has the most conductive soil in the US what does that say about his antenna tests? But you haven't lived in all terrain types in every...

For that test between your two friends to be valid both antennae need to be on the same pole and in the same location with the same radio and coax otherwise it is a totally pointless exercise. So you don't think Marconi is going to suggest later on in this thread that a quarter wave is better...

What do you want me to prove? I didn't state a belief but rather a fact, Eznec cannot emulate real life. It cannot take into account attenuation, it cannot take into account the difference between the materials our houses are made out of, coax differences, differences in soldering techniques...

....And just to add to that, back here I'm known as Doctor Nav. I've just developed my new software for analyzing people called surprisingly 'The Doctor Nav People Analyzer' TDNPN for short. This software is also based on the NEC MiniNec algorithm but also the Turbostrad technology just recently...

Doesn't matter who's software or who's algorithm it is based on, it is still programmed my men. Men are not mother nature, they base their software on what they think is a reasonable simulation of mother nature. The computer game 'Total war' is a computer simulation of a war, there are no real...

I disagree, the software is only as good as the person who programmed it and the knowledge he had at the time. Unfortunately Eznec cannot emulate nature, it can only emulate one persons version of how nature works.

Marconi wrote Are you suggesting that a quarter wave ground plane is better than an i10K, a Sirio 827, Mr Coily, etc at AM, FM and DX? But does your version of the truth use real world events rather than that crock of pants Eznek software that Doc probably wrote:oops:
