I got a chuckle out of the thought the 1/4 wave whip should have been better than the Wilson base loaded antenna. Here is another example where intuitive thinking fails in the shadow of theroy. The received signal induced into the element is vertually the same level in both antennas, so why...

Look at it this way. Take a dipole and mount it vertical. It is a complete antenna. Turn the bottom half horizontal, you still have a complete antenna. Add 3 more same length horizontal elements and you still have a complete antenna. This config is normally called a vertical ground plane...

How are you measuring SSB power? Normal speech will only result in about 1/4 or less average power indication out of a full 12 watts power output. The peaks are there but the metering cannot follow the power changes as you talk.

Why not get any copy of the ARRL antenna handbook that discribes all this? No matter the year of the book, the theroy never changes.

I know your not going to understand this but it's worth a try. A 5/8 wave length element has an 'excess' of capacitive reactance to the ground around it. With this situation the matching section counters 'with' inductive reactance to canel it out. When the proper setting is found for 50 ohm...

Here is a cheaper way of getting good results. A Noise Bridge is often advertised used at about $30 for a PALAMAR unit or about $70 from MFJ. Build a """"flat""" 50 ohm load as a reference piece of test gear. Connect the Bridge to your receiver and the antenna port to the flat load. Adjust...

Eric, I looked at the thread I think prompted this. You brought it on with your own sharp tonuged responces in a number of replies. Review it and see if maybe you should have been a little more diplimatic. After all this is CB so expect what you hear as normal. With a Gen class ticket, why...

Your are in information over load with no way to sort it out. You need to go the school to learn AC impedence theroy first then another course on antennas and transmission lines. Then what you hear here will begin to make sense and be able to reject myths and hear-sey. Until you do you will...

A loading coil "never" improves an antenna over a full length at the frequency of operation. A full quarter wave has an input impedence of close to 70 ohms not 50. As you go longer to 5/8 wave, the input impdeance goes lower such that you must do an impedenace transformation up to the coax...

The 6LF6 tubes are classed as receiving tubes and are aged and ready to go out of the box. They were uses in TV as a horizontal sweep power tube. During the TV days they never required any aging to be used during a service call or repair because the original design and use was not for...

When the amplifier is keyed up, the input is switched to the amplifier input circuit. The input circuit is not even a close match to 50 ohms. What would need to be done to correct this mismatch is unknown until some one who understands matching gets a look at it to determine what to do. It...

Can't get anybody to work 6m, 2m, 1-1/2 or 70 cm let alone 10 Gig. Only time 10 gig is used is at contest time on a general basis from high locations. It takes specilized investment and most of us won't make it unless there is some local area interest. One would be better of with cheaper...

Likely the power supplies are switching types. They nearly all cause QRM due to the switching transients cause by their square wave switching oscillators. The transients have harmonics all over the bands and into the VHF spectrum.. It's a crime for any mfger to put put out such trash without...

Just a suggestion, why not make a Fan dipole out of the whole assembly and eliminate the switch box and all the baluns and the hassle. Good luck.

Co-phasing antennas. At 11 meters, a 1/4 wave distance is about 8 feet. The antennas need to be at least 8 feet apart to realize any gain benifit. Even then the radiation pattern is not circular but close to a figure 8 pattern when the distortion of the pattern is taken into account from the...

W5LZ, Your right I messed up on the gain DB. From a reference of 4 watts, 3DB down is 2 watts. 3DB up is 8 watts. Thanks.

Not trying to insult anyone but these antennas are nearly the same in 'electrical' performance. Why would you expect any difference in signal over the same path? For there to be a difference, the following parameters would have to be different. 1. The length, affecting radiation efficiency...

I don't think you still understand the issue that is possible. On a standard Fan dipole, the question is how does the RF power on any band know which element to use most? The answer is the pair with the closest match to the feedline "for power tranfer". Providing no other element is resonant...

I would like to bring up something most miss about a Fan arrangement. Trying to do a Fan with 160 and 75/80 can present a problem with feed match. Here is how it can go. Say on 1.9 if you have a good SWR on a single dipole than add an 80 meter element guess what you can end up with? 1.9 x 2...

For $20 you can get a window unit from Wallmart. An auto fan is meant to run high speed and move enough air to be useful for that application. Good luck.
