NEC is written from the standpoint of protecting people, not necessarily equipment. Granted, more often than not, when it comes to grounding/bonding, what's good for protecting people is usually als
and 1-5/8" Cablewave heliax. I looked through my stock here and find Amphenol 272105 (crimp), Huber+Suhner 11_716-50-7-4/003 (clamp) and 11_716-50-7-2/003 (crimp) for RG-214 and/or RG-393, and I als
I think you meant to write the jacket is tough, not that it's pretty. Anyway, the composition of the jacket isn't the issue. If you get even the slightest nick in the jacket of Superflex, due the he
Unless they've come out with something since then, last time we looked at using or stocking Trilogy we decided not to as they only made smooth-wall aluminum shield cables. As far as smooth-wall, we
Even though Commscope had less loss for a given diameter cable, it was often just as cheap to upsize regular Heliax, and then I didn't have to risk having the tower crew put a kink in a line and eat
No, the later ones were marked "-50A only" because there was also an LDF5-50B that came out near the end of the LDF product line which used connectors that were incompatible with LDF5-50A due to dif
"Tape and taffy" has been the standard way of weatherproofing connectors in the commercial world for the better part of 50 years. Applying a later of Scotch 88 first is known as a "courtesy wrap" -
I believe you're speaking of a second-order mix. Third-order mixes tend to be more problematic in a repeater installation as they yield "in-band" mix products. Third-order mix amplitude varies as th
I have the same generator, but running on LP (no NG around here). No problems whatsoever. -- Jeff WN3A -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/a
You didn't say what model cable. FXL-540? You really don't want JMA or any other compression connectors if you're going to try to install them with hand tools. You'd be much better off with regular
If you want "the good stuff", Belden or Times would be your best bet. We had a contract job a while back that required several thousand feet of RG-213. Most of the cable runs were indoors. We used J
Sorting through boxes of connectors and thought I'd offer them here before they end up in one of the tubs destined for Dayton next month. Starting with some 1/2" RFS connectors: - RFS/Cablewave #7388
The thickness of the strap has very little effect on inductance. You didn't say how long the run length was between the exterior aluminum plate and the interior plate so it's hard to gauge what effe
I started to doubt my memory after I read your email, but I believe I was correct as originally written. A 12" length of wire with a diameter of 250 mils (about #2 AWG) has an inductance of 275 nH.
Grover. I don't know how well this is going to come out in email without me making a typo, but... Straight wire: Inductance = 2L * ln( (2L/D) * ( 1 + sqrt( 1 + (D/2L)^2 ) ) sqrt( 1 + (D/2L)^2 ) + u/
Soft/annealed copper (I don't think "soft-drawn" is a correct term) is preferred as it's more flexible and has slightly better conductivity. Hard-drawn has a higher tensile strength making it useful
I don't think MCPT will work ideally with EZFIT 7/8" connectors. The MCPT has different positions for the jacket-cutting blade, one that is closer to the shield-cutting blade and one back from it. I
The other big problem with long runs of Ethernet is the increased likelihood of equipment damage due to lightning or ground potential differences. Near strikes can/will blow up the phy or magnetics
Maybe he meant an "SJ cord" connector, perhaps better known as a cord-grip or a cord-grip connector? -- Jeff WN3A -- This email has been checked for viruses by Avast antivirus software. https://www.
<cough> Commscope <cough> Even before Commscope bought them, we had a lot of issues with Andrew LDF4 factory jumpers. The common problem was that the dielectric wasn't cleaned off the center conduct
