Default the latest merlin commercial .


i would post a link to the thread ..... but coolio doesn't like links .....

********************************************

"55 merlin
by coolbreeze Ľ Sun Feb 26, 2012 6:52 pm

When the merlin was first concepted it wasn't intended to out perform a 5/8 wave antenna. It was a sturdy, low wind load and a small footprint which is helpful in HOA's

Concept of the design. The antenna has a ľ wave hot element, and ľ wave radials. Basiaclly it is a Ĺ wave dipole. But it is a top loaded hot element which is where some of the performance comes from.

Initial set up of the antenna is easy. A few parts and you are done. As for tunning. The antenna is extreemly broad banded. And it is so consistant in its tunning that you only need to set the antenna up at the provided marks and its 99% dead on. It was a suprise that it is that easy.
At one time I had the antenna tuned on 27.8 and was able to talk on 10 and 11 meters and not go over 1.3 swr.
Tunning numbers
27.185 48 ohms and x=0 1.0 swr

26.000 44 ohms x=0 1.3 swr

28.000 55 ohms x=10 1.3 swr

26.9 to 27.5 1.0 swr


Now for some real world results. ( no link provided )
When I first put the antenna up the majority of locals are with in a 12 mile radius.
To those guys I had equal tx and rx signal. But when we started to further test at longer distances is when the performance started to shine. It was never stated that a ľ wave antenna can out perform a 5/8 in radiated power. But just like others have clamied in the past that ľ wave antennas have performed better ( star duster ) ( also less tvi ) is due to angle of radiation. Now booty I know you have a problem understanding this so pay attention. Take off angle of any antenna is one of the biggest factors. If you can not place the signal where you want it to be your not going to get out. This is one reason why flat beams are used during skip. Low angle of radiation!
Just as a quarterback, or baseball player. If they canít put the ball in some ones hands, or over the back wall it doesnít matter how hard they can throw or hit.

An imax has a high take off angle. Which is why most all antennas out perform it locally very easily. 5/8 wave antenna arenít as bad. The merlin is much lower.

People who have used the merlin, tested and compaired it have 9 out of 10 found the same basic results.

With in 12 miles. The merlin is on par or a tad under the 5/8 wave ( 10k which is the best of the 5/8 )

The further you go out the better the performance picks up. Why? The signal is transmitted lower to the ground and the curve of the earth doesnít effect it as quickly.

Test.. me and yote. Iím in Alexandria and yote is in Baltimore. Roughly 30 air miles. He has the merlin and I10k up with a radio into a 2 pill. I am in the mobile sitting still. On the 10k I had zero signal. Not a garble or a needle wiggle. On the merlin I had a solid 1.5 -2 s units on him, perfectly clear. ( no link for this either )

Test. Me during skip on ch 6. I could change antennas in 8 min easy. I have a winch set up on the tower and itís a quick process. I changed from the merlin to I10k radio into a magna 200. No contacts on the 10k, contact on the merlin. Kinda simple there but still no link.

Me locally. With less power I have easily been able to talk further then my other locals, that was unitl they got merlins also and made it tougher. I had to pump it up then. But at the longer distances I was clearly doing better then the I10k. I can not be a good rx test due to the local transformer static.

Wrangler a local guy. He has had the jo gun 5/8 and the 7/8 ground plane, and an imax. He now puts 2 more s units on his local group, along with having less static in his rx along with 2 s unit gain! He can now hear a few of them barefoot where befor they needed power on. 4 other locals have a merlin now all with basically the same results.
I will say one guy has one and does not have these results. But he does tx into the side of a mountain facing our direction.

Yota test. Now this is where blow hole gets his 15 db gain increase.
I do not have a copy of the post he made. Carl deleted it since he is a tool. And I am not going on maul droppers to go and find it. But yota had 4 antennas merlin, 10k, coily Excalibur ( his 500 dollar base antenna) and a penetrator 500.
Several test were done on several days. At 30 air miles using a 2x8Ö.
( these numbers are not perbatum but you will get the idea, go find the post for accuracy )
Penetrator 500 6 s units
Coily 7.5
10k 9
Merlin near the corner!
I did not do that test. And yota is a huge coily fan and was highly supprised the coily lost.

Now as for the post link of the guy bitching. Yes that is a tap that broke. The guy didnít want to wait for the antenna as it was ( they are made per order ) Also the tap in no way affects the operation since its in the center no current part of the antenna. ( laymens )
Also the guy complaining was having radio issues that were not related to his antenna system. You should be able to see that comment elsewhere.


Bottom line is this. Yeah with all the cb comments that fly around, and the number of ľ wave one would think a 5/8 has to do better. Well real world results donít lie.
As Iíve stated before. There is more (75%) bad information that goes around then good info. More ghost stories then not. A lot of should have, would have, could have with nothing to back it up. The reading is here for ya. I am sure you can come to your own conclusion. But this is an information post. Donít shit it up. "

***********************************************

it's a damn shame he has to say dumb stuff and make silly across the board statements/claims . i think 55 would have sold more merlins if it weren't for a few over zealous fanboys saying stupid stuff . the starduster was and is still a decent antenna .................

Everything after the swr test results was just anecdotal. Based on his description the antenna sounds to me like quarter wave gp with a loading coil on top. Probably why he can make the statement that the antenna is broadbanded. So is my Heathkit cantenna.

Quarter wave ground planes make good antennas though and can work well.

When I was a child
I caught a fleeting glimpse
Out of the corner of my eye.
I turned to look but it was gone
I cannot put my finger on it now
The child is grown,
The dream is gone.
but I have become comfortably numb.

Egg-zactly. A ground plane I built with #14 wire and a crappie pole was also extremely broad banded (which is in a thread somewhere on this forum). I attempted to have an informed conversation with one of the guys (maybe the same person) associated with this antenna a while back. Not even going there again.

There's no reason to believe this antenna will not perform well-- but the same could be said for any similar design.

Where is the evidence that supports these statement? Because HE said so? I'm sorry; none of what he said right there makes a lick of sense to me. Anyone else?

A 5/8 wave is a 5/8 wave is a 5/8 wave, and their pattern is both known and predictable. The only disadvantage with the Imax has - is the fact that it may slightly have more loss than an aluminum 5/8 wave - due to the fact that there is more loss in its matching coil design. Locally, they work as well or better than many other antennas I've heard around here. How much lower of a radiation angle can one really use when it is mounted at 1 wavelength above ground anyway?

Sorry; but do I smell snake oil?

This thread is like dťjŗ vu all over again. Is there any new information here, or is the pot just being stirred?

BOTH



"An imax has a high take off angle. Which is why most all antennas out perform it locally very easily."
"This is one reason why flat beams are used during skip. Low angle of radiation!"

"Test.. me and yote. I’m in Alexandria and yote is in Baltimore. Roughly 30 air miles. He has the merlin and I10k up with a radio into a 2 pill. I am in the mobile sitting still. On the 10k I had zero signal. Not a garble or a needle wiggle. On the merlin I had a solid 1.5 -2 s units on him, perfectly clear. ( no link for this either )"

i can put 2 s-units on a meter over 30 miles away barefoot (from the Pocahontas state park area in chesterfield to stony point , over 1/2 way to emporia off 95) . i'm not impressed by a antenna that needs a couple hundred watts to do it .
