Moleculo how are you doing sir, hope all is well with you and the family? I just stopped by to say hello and enjoy your holiday season sir.

WHAT MAKES THE SK606 DIFFERENT FROM THE SK607 TUBE SOCKET? CAN U MODIFY THE 606 TO WORK WITH THE 4CX600JB TUBE?

Hello Toll Free, I agree with everything you said. The tubes were given to me, I have about 5 of them so I am going to build a 2 tuber and see how it performs. AB1 of course lol lol. Take care bro and we will see how the project gos.

Good evening paws , and thank you for the information. The prices on those tubes are between 1400 dollars and 2200 dollars. Must be some great tubes for that price .lol lo. Thanks again sir and have a great day.

Good evening to the forum, does anybody use these tubes(4cx600j or jb)? How does it perform and what is the gain of this tube? SHOEMAKER.

THANK YOU W5LZ FOR YOUR OPINION , VERY IN TERESTING I NEVER THOUGHT OF IT THAT WAY. I WILL LOOK UP THE HEIL ELEMENT. TAKE CARE AND THANKS AGAIN.

HELLO AGAIN AND THANKS FOR ALL THE COMMENTS. THE MIC 60SOUNDS GOOD, BUT I SAW A HEIL PRO 30 STUDIO MIC. WHAT ADJUSTMENT WILL I NEED TO MAKE TO USE THIS MIC( IF I CAN)?????????

I would like some opinions on what you think is the best desk mic for the Kenwood ts440s and why?

GOODDAY AND HOW IS EVERYBODY DOIN? IN MY OPINION THE JO GUNNS ARE OVER PRICED AND OVERRATED, I DO NOT BELIEVE THE GAIN FIGURES. MACO ANTENNAS ARE GOOD. I RAN THE 4,5,6,7,AND 8 THROUGH EZNEC AND THE 7AND 8 ARE ALMOST EQUEL. AS A MATTER OF FACT THE 7 HAS 0.20 MORE FORWARD GAIN THAN THE 8, AND THE...

HELLO MOLECULO HOPE EVERYHTING IS WORKIN OUT WITH THE ANTENNA. WHEN DXER AND MYSELF WERE MODELING THE ANTENNA WE NOTICE THAT THERE WAS A WIDE SPACE BETWEEN THE REFLECTOR AND THE DRIVEN ELEMENT, IT SEEMED REAL ODD. SO WE MODELED IT THE OPPOSITE WAY AND "BOOM". I WAS AMAZED AT THE ERROR(BUT NO ONE...

HELLO PEAKABOO, ANY QUAD WITH MORE THAN 2 ELEMENTS CAN BE DIRECT FED AS LONG AS IT IS BULIT CORRECT. I RUN A 4ELEMENT ON 30FT BOOM THAT I BUILT(EZNEC PLUS) DIRECT FED 50OHM COAX NO ISSUES AT ALL. WITH MODERN TECHNOLOGY ALL IT TAKES IS KNOWLWDGE, PATIENCE AND YOU CAN BUILD ALMOST ANYTHING.

GENTS THANKS SO MUCH FOR YOUR IMPUT. I THOUGHT IN WOULD BE VERY INTERESTING TO POST THIS QUESTION BECAUSE I ASSUME OTHERS MY HAVE THE SAME QUESTION IN MIND. I AM SATISFIED AND WILL GO WITH THE 6 ON 31FT BOOM, BOTH OF THE ANTENNAS IN QUESTION I OPTIMIZE FOR SWR. THE FRONT TO BACK ON BOTH IS 36DB...

THIS ANTENNAS WERE DESIGHN ON EZNEC PLUS BY ME. BOTH ARE 6 ELEMENT QUADS AT 60FEET, 6 ELEMENT 31FT BOOM= 17DBI(14.85DBD)/ AND 6ELEMENT 48FT BOOM 18DBI(15.85DBD).(I SHOULD OF DONE THIS FROM THE BEGINNIG). THESE ARE THE REASON I ASKED THE QUESTION. IS IT WORTH IT?

WILL FERRITES TOROIDS FROM AMIDON WORK? 43 MATERIAL FOR EMI/FRI SUPPRESSION ON 20-250 MHZ.THEY HAVE DIFFERENT SIZES, DEPENDING ON THE DIAMETER OF THE COAX.

SORRY CORRECTION (WILL). THANK YOU MOLECULO, I WANTED TO KNOW IF IT MAKES ANY SENCE TO BUILD A BIGGER ANTENNA WITH ONLY A GAIN OF 1 DBI BETTER.

What about direct fed, build the quad for direct feed and run the heliax straight to the driven element> shouldnt that work ?

Hello everybody. I have a question about dbi. Whats the difference between an antenna with a 17dbi gain and a 48 degrees beamwith compared to an antenna with 18dbi gain and a beamwith of 42 degrees, or can you see any changes on the recieving end with 1 dbi of gain? Thanks in advance for your...

GE RICK C, I OWN A COPY OF THAT BOOK, ALSO ALL 3 EDITIONS OF THE QUADS NOTES WRITTEN BY L.B CEBIK W4RNL AND BOUGHT ALL THE QUAD SPEC FROM ANTENNA X DONE THROUGH EZNEC. MY QUAD WAS OPTIMIZE FOR FORWARD GAIN, F/B GUT OF COURSE THERE WAS THE OBVIOUS SACRIFICE BANDWITH. I ONLY DESIGN IT FOR ON...

Hello Marconi, I used up to 21 segments and the dbi gain only changed by .01.The 11 segments wre the loweet that i used ,but as far as accuracy (on paper) I think its on the money.The dbi @ freespace is 12.59 and like I said before @60 ft its 17.92dbi.When I am finished building it i will inform...
