WILSON 400 (50 ohm):

  • They have 3.5db loss @ 700 MHz, 6dB loss @ 2100 MHz per 100 feet
  • It is perfect answer for business employments. It is profoundly suggested for different communicate radio wires furthermore prescribed if the approaching sign is OK to poor.
  • They utilize N-Male connectors.



  • The greatest link length relies on upon the signal quality alongside the increases and misfortunes that happen all through the framework.
  • It is desirable over utilize link of length 100 feet from intensifier to reception apparatus.


75 Ohm VERSUS 50 Ohm:

  • CEDIA Industry standard is 75 Ohm while for huge business structures it is 50 Ohm

    Similarly 50 Ohm has somewhat less misfortune per 100 feet of link.


    Business review links are accessible in bigger amount in 50 Ohm just (i.e. 600 cable, plenum cable)





Apple marks its entry to future of Wireless Technology

Talking about the trusty old headphone jack – 3.5mm one which we all use to connect earphones/headphones and other audio products. Apple is highly rumored to be getting rid of this port. There have been leaked images of iPhone 7 dummy units, there have been reports from business journals and industry insiders and there now are a multitude of products on the market before this sweeping change is announced on Wednesday.
And when it happens it will be a sweeping change. Most people associate the headphone jack from the Walkman ear in the late 70’s but this is a technology that’s been there since the late 19th century. It is an off-shoot of the 6.35mm jack which is still used in pro audio gear like electric guitars and what not, but originally it was developed for telephone switchboards.
Make no mistake, what we’re witnessing right now is the calm before the storm because come September 7, lightning is about to strike the 3.5mm headphone jack, and for the part it will be a good thing unlike all the hullabaloo that’s been created by the leaks, rumours and blogs.
The most obvious disadvantage of losing the 3.5mm jack is that if you have an existing headphone that you’d like to use, it will be rendered useless with the iPhone 7 or whatever Apple decides to call it.
In addition to this, if you’re the type of person who likes to charge the phone and play music through a headphone or an external speaker via a wired connection, then that will be a problem.
Also, for audio purists the problem is that wireless audio or any kind of digital signal is inferior to an analogue signal. That’s what they claim at least, or for the time being that’s the perception.
The incompatibility will also plague inter-operable with other gadgets like PCs, Laptops, Android smartphones, basically anything with a headphone jack.
Progressive for the sake of wireless and digital audio
The big takeaway is that this will further the cause of digital audio – be it wireless or wired. It can also theoretically help Apple improve other features like the battery life, speaker and microphone performance, by outfitting better performing parts with the added space.
If a headphone has to use a lighting cable, the DAC or (digital to analog converter) must be inbuilt in the headphone itself rather than being in the mobile device. So this would mean that very good headphones could achieve better sound output without the constraints of the quality of the iPhone DAC while very bad headphones with a DAC worse than the iPhone DAC producing below par sound performance results. Overall, I would believe that the headphone industry will see more focus on innovation around the DAC and wireless technology which should be exciting times for our business.
In simpler terms, this means that the DAC which is always on the iPhone logic board will now transfer to the headphone or earphone itself. Apple has had the MFi plan for lightning certified headphones for two years, so Apple will have a base standard of what a DAC has to be like and what quality of audio it has to deliver for a headphone or earphone to get its certification.
Apple actually has some very stringent guidelines for products that have the MFi branding and it goes without saying such high standards aren’t met by most earphones or headphones which use the standard 3.5mm jack.
While traditionally wireless connections for audio were deemed to be inferior, there’s with new standards like Bluetooth 4.0 and the incoming 5.0, the audio signal degrades more over an analogue path like the 3.5mm jack. As mentioned earlier, it is also dependent on the quality of the cable being used and the type of material the jack is made of. Digital signals just standardize this.
More importantly, right now the entire signal path is not dictated by the headphone. Even if you have the best possible headphone, it is straddled by the limitations of the iPhone DAC. That will change with this shift.
People feel that Apple is nudging the industry towards a fully wireless future.
The basic understanding being that Apple’s vision for people listening to music on their iPhones is to do it using wireless headphones using Bluetooth connectivity. It would seem Apple’s aim here is to offer consumers the convenience of wireless music listening.
