How does the 4 Element Maco compair to the old 4 element Mosley? I have a SkyLab that is just great for talking local when its not to noisy, But I'm looking into getting another beam as my father lives aproxemently 50 miles away from me and the Skylab just won't quite make the trip. I plan to keep the skylab for local use and add a switch box. Which Beam would give me more bang for the buck.

If you only need 1 polarity, the Maco will perform almost exactly the same as the Mosley mono bander. The element spacing is slightly different, but the gain is the same.

You might be disappointed. Think this one out. If you are incapable of contacting him and you change your antenna, you can contact him ie your signal may reach him. HOWEVER if he does not change his antenna his signal may still not be strong enugh to reach you even with the better ears. His signal must also change as well. He will also need to increase both his receive and transmit as you did.

I experienced this "One Way" signal myself. I was conducting what in the Ham World is called A Worked All States or Contact Net--exchange signal reports and QSL cards. Well I was running a couple of hundred and the people heard me OK, BUT they were not running a couple of hundred. I could NOT hear them since they were running ONLY 100 or less. The lesson here is that power and antennas are a two edged sword. Both increase your range but it does not do you any good if the stations answering do not have enough power to reach you with sufficient strength.

Bottom line, send you pop an antenna as well so both of you will be on the same page and be able to engage in conversations clearly and easily.

DE,

Antenna gain is different from amplifier gain.

Since antenna gain is almost exactly reciprocal, if both stations are running legal CB power, and one station changes to a higher gain antenna which makes his signal heard by the other station then they should be able to make contact both ways.

Amplifier gain ('a couple hundred') will not improve your receive at all. Unless the other station runs 'a couple hundred', you do not have a reciprocal path. Now if you both ran the same power, and you both have essentially the same receiver sensitivity and selectivity, you have a reciprocal path. Even if only one station increases its antenna gain, you still have a reciprocal path.

Gain works on receive the same way it works on transmit. That's the beauty of antenna gain vs. amplifier gain.

I have about 3 S units on my Father, He can hear me but faintly. So by me going to a beam this should solve my problem correct?

It will help.
