Hi Rommam, this has nothing to do with signal level the switching voltage for the LNB between Horizontal and vertical frequencies is as follows...Polarisation switching is controlled by DC voltage supplied by the receiver. 12.5v to 14.5v gives vertical and 15.5 to 18v gives horizontal polarisation. The openbox supplies 14.7 so it never switches from H to V on some channels well at least both mine did. An inline amp wont fix this.
Dont understand how you think foam insulation carries the signal as this is not the case you need a good quality cable with screen and and shield for instance WF100 the foanm dialectric is an insulator. Take the fact that you use cable joiners the foam dialectric is cut on those. Sorry mate appreciate your input but question your facts anyway BER is 0 and working fine:caz:
Steve i have been on more training courses than i care to remember over a very long period of 18 years and i can assure you the dielectric insulator carrys the db signal from lnb to receiver and any disruption in this causes signal loss! Even an f type barrell is not recommended as it will still introduce some signal loss although i have used them in the past myself but if you look at these barrells they are specifically designed for the job of joining cables to allow a continual flow for the dielectric,albeit your fplugs have to be fitted correctly for the barrell to work correctly, by allowing the foam or plastic insulator to rise out of the tip of the f plug by a couple of mm so it touches the the solid plastic dielectric on the barrel when both fplugges are fully tightened.
Electrical connector blocks are most definately not designed for this!!
Outer sheath = obviously to stop water/moisture ingress
Sheild = an interference barrier to prevent unwanted noise distorting the data!
Braiding = Acts as a ground and helps the inner core do its job correctly
Inner core = Voltage!
I have explained what the dielectrics job is on co-axial cable already!!
This is why its not a good idea to crush cables or introduce sharp bends on the cable while installing as it crushes the dialectric causing signal problems although foam is the best cable to use as the plastic dielectric crushes easily...
I,m sorry but i would not recommend anyone does this modification and look for another solution to remedy your openbox problems.
