I will like to know the effects of using two pieces of coax with different velocity factors? Joined with a N type connector

i am runing the map pro 4 , by itself with just a compressor before it, i am also using the lcd screen to change the freqiency, but the power level will not chance via the lcd why is this?

i always wanted to ask this question, why did your company make a follow-up to the maxpro3+ ( the latest version maxpro4+ ) then now you are stating all the benefits of the older version , I have both versions , I like the maxpro3 over the 4 . Please respond with some clarification.
Thank you.

hi , does any one here have a good explanation of how to select the ultimate spacing for multi-bay antenna system?

for example a 2 bay system , i was told by the manufacturer it will be .80 of a wave.

so for example if my antennas are spaced at .75 of a wavelenght, what wavelenght should i cur the cables to 1 wave
.75 wave
0r 1/2 wave

i have some ststic noise on the air currently, do you know what can cause that? and a fix for this problem.

does anyone knows the formular for getting the lenght for the inter bay cables for a 2 bay or a 4 bays antenna system?

Can you guys state your views on folded dipoles vs. regular dipoles...?
I will like to know your experiences with these antennas

i am not loking for a completed amplifier, i am building the amps to save money , so all i need is something like a max pro 3 with a lcd diaplay, and a few controls on the lcd to read the frequency, read the power level and adjust the power level from 0 to max.

I will like to know if you can make an RF output level control (attenuator ) using a LCD to display information , I will be using a 300 watts and a 600 watts on two different transmitters, I will like the LCD to display the frequency and the power level. that mean you will provide me with the mono e...

When ordering write under comments: This is for MAX PRO 4
and I will make sure you get the proper software for this unit
installed.

you ditnot answer my question,
can they be used on either unit?

Can I inter change the LCD display from one unit to the other, I have one of each of these units, one of my LCD broke...

Do you sell these LCD by it self?
If yes what is the price?

What wavelength or fraction of a wavelength will give the best results for stacked dipoles?

¿puede usted justo utilizar una batería como almacenaje, con los paneles para cargar la batería?

is it better to pull the hot air out the enclousure?
of is it better to blow the cool air over the heatsink and into the elclousure?

i will like some feedback on the Times Microwave LMR-900 coax
also the andrews LDF4-50A coax
and finally the Belden 9913

can you get good results with coax that has a joining within the run?

so you are saying to run the system at higher voltage , we will use less amprage ?

please explain the meaning or duty cycle?

300watts

so now the big question.
when will you make a transmitter that will run on a 12 or 24 volt system.
48 volts is to many battries (4)
