Series 59 cable can create intermod within the cable, yielding 6MHz beats and raising the noise floor. At lower freq's its fine, but as you increase in frequency(> 1GHz) there is more propensity to create the CPD-Intermod issues. Also Dish (and Direct) is not MoCA, its a proprietary multi-room...

Do you have an old wireless phone, 4G phone, or a cel tower somewhat (.5 mi or less) away? A single loose connector or a exposed wire can introduce noise in the Muti-room DVR band that Dish uses, causing the hopper to break communication with the joeys and eventually orphaning them. I would...

Anything after the sat lines entering the node MUST BE TIGHT!!!!!!!! Cannot be stressed enough!!!!! A loose connector (less than 5 degrees from fully finger tight) in the hopper joey setup is death to the system and results in joeys searching for hoppers and then the stuck 1303 screen of death...

You are correct, MPEG4 requires less data to assemble the frames, the strength of the signal beam needs to be sufficient to create a sufficient SNR that the receiver can distinguish signal from ambient noise, as long as the strength of the signal hitting the LNB (or at the end of a long run the...

Not to beat an old horse, but first off not all PV is solid copper, 2nd not sure that each box is swept to 3GHz (Testing seems to conflict), 3rd solid copper is for powering the LNB(s), has ZERO effect on the signal at the 1+GHz range, and if truly solid is wayyy more expensive to produce from...

Sadoun shows an old school 11 that was feed-thru (I shudder, its the top one, the pico-macom) which is what your speaking of, where the CC fed thru the connector body and was inserted into the port. It bent the heck out of the port contacts, sometimes shorting the internal contact to the outer...

Perhaps, but its not used as the UV protectant in most PVC cables (at least ones of any quality). Each cable manufacturer will have a proprietary blend of PVC and a "protectant", some protectants merely strengthen the bonds in the polymer, others will change the molecular structure to tighten...

The "indoor" series does have the UV stabilizer additive in it. Some people when ordering see "outdoor quad shield" and order it thinking that means it has the messenger for aerial or sat usage. So the idea was anything that is a plain cable is called "indoor", anything with a messenger or...

OH NO!!!! NEVER, EVER, PUT ANY "GOO" IN THE FACE OF THE CONNECTOR. This is the worst thing you can do to try and mitigate moisture migration! What happens is the "goo" fills the nut, then when you put it on the port it hydraulically forces the extra goo into the port, this causes the impedance...

perfect vision from a lab standpoint is some hard to deal with stuff, their manufacturer WAY over uses adhesive on the dielectric, thats due to a high coefficent of expansion in the copper core vs a low coefficent in their chosen dielectric foam, by gluing the heck out of the dielectric to the...

This is the issue we have pointed out for years to DirecTV, lack of proper port seals equals GUARANTEED trouble calls. You have it correct to some degree, water penetrating thru the threads is BAD!!! it corrodes the threads isolating ground, creates shorts from the CC (battery) to post (ground)...

A few comments quickly. 1. CCS has better propagation than solid copper, i.e. for high frequency rf, ccs is a better cable. For power passing CCS sucks and is high resistance as you raise the current flow, hence why DirecTV is lowering the amount of power passed over the wire. Reality going...

There is a reason those PPC connectors DO NOT have a o-ring or "washer" in them. Notice any connector of quality doesn't have them, because they can cause the ground to float, raising the potential for issues later such as lightning strikes, equipment damage, and the dreaded pixelization and...

I don't know about imitation cable, but I have seen people visually mistake LMR 50ohm cable for RG-11 (I've done it several times in the lab) Seems right until its connector installation time.

In the past few years alot more development has begun into the cables we're using. As bandwidth expectations increase so has the need to redesign cable we once were fine with because it passed sufficient signal, gone are those days where a soldered together splice mid-reel was common place. A...
