Antenna efficiency can be defined in a couple of ways: (1) Radiation Efficiency Rad Eff = (Power_Radiated)/(Power delivered to antenna ) (2) Total Efficiency Total Eff = (Power_Radiated)/(Power The Transmitting Radio Outputs) The difference has to do with mismatch loss. The...

Bandwidth isn't a measure of efficiency of the antenna.

Just a qucik note regarding coax switches. I had a alpha delta 4 position switch, I was getting intermitent contact one day, so I opened it up and once I saw how it was made . I fixed what was wrong put the cover on it and listed it on ebay all within a 30 minute time span. I sent Bob85 a few...

Possibly Phase differences?

What the hell is a gamma dog bone? Is this a fancy new word for the shorting strap?

What in that picture makes you think it is a nice clean build? the fancy blue lights? for one, it looks like poop wire lengths all different as Mack said the transformers look like a blind man installed them, besides a host of other bad rf practices.

Mack were you better friends with Kiki or John? I think John gave you the radio to leave his wife alone...

SWR is nice and all but where is the antenna actually resonant at?

I heard this is the best out there on market now.

What defys logic is using bouncing SSB signals to try to see any difference in signals. Please for the love of god get someone on AM to throw a dead key for 10-20 second and switch antennas, pick several stations. Use the radio with the round analog meter from last test. That would probably be...

I cant explain what you are seeing since I am not there, But i can see you are testing to people with Beam antennas in at least 1/2 the tests. I assume you are still using SSB, and I can only assume you are using the S meter. Not much has changed in this thread but the date. If there was 1 db of...

LooseCannon, another great post. What the hell did you eat today, your like butter on a roll. :thumbup:

LOL funniest post in this thread yet. By your advertising schemes you dont know crap about antennas, from your forum posts you dont know crap about antennas. You are a decent machinist Ill give you that but kale's got you on that too.

I drilled a hole mounted the bnc made a 1 turn 1" ID coil inside connected to center of bnc and ground. works like a champ.

Let's put the books aside Coily. i guarantee I have tested more antennas in real life than you ever copied. You have no understanding of theory and your test results and product show that. You think somehow if the MFJ reads low your antennas perform. I know how to run a lathe but Ill bet you can...

Bingo, and this is what happens when guys who don't understand what they are reading and what it pertain's to they try to craft it to there situation or think it is an answer to what they are doing.

This has to be one of the best posts ever on WorldWide DX forum. :thumbup::thumbup:

A test range LOL Ok tell us what your test range is? parking lot? If you dont know how to conduct the test the right way your data is useless. I would have to say from what i have seen and heard your data is useless

No reply to the audio increase claims ...LOL go drink another beer it might help you understand the arrl book. It doesnt matter if there is 21" there or not it is the actual physical size that makes a difference a 6" disc on top would have more area then your 21" of wire in a ball.

Depends on the day of the week or year right now .... a vector, 1/4 wave gp, dipole, 2 element flat side
