Commercial Grade 5G Anti-Interference Feed Systems

Lost your C-band satellite signals because of 5G wireless interference? No problem. Tek2000 now carries a wide variety of commercial grade orthogonal feed systems and components that will clear up your satellite reception in no time!

5G interference is caused by the undesired combining of several stronger RF carriers (e.g. f1, f2, f3, …) from one band (3.5 – 3.8 GHz) entering a nonlinear device (e.g. LNA, LNB) and producing unwanted frequencies in an adjacent band (3.8 – 4.2 GHz) that interferes with a much weaker c-band signal (e.g. fc-band). The nonlinear device causes harmonics to appear at the output: 2xf2-f1, 2xf3-f2, 2xf3-f1, etc. This is known as intermodulation distortion and is the reason why your c-band satellite reception will be lost if there are 5G transmitters in your vicinity.

Here is an example:

5G RF carriers: f1=3.5 GHz, f2=3.7 GHz, f3=3.75 GHz

Interference Output: 2xf2-f1=3.9 GHz

Interference Output: 2xf3-f2=3.8 GHz

Interference Output: 2xf3-f1=4.0 GHz

Notice the resulting c-band interference at 3.8, 3.9 and 4.0 GHz. In reality, the 5G wireless provider may be using dozens if not hundreds of different carrier frequencies between 3.5-3.8 GHz, which will result in intermodulation distortion across the entire upper c-band spectrum.

The only practical solution to this problem is to suppress the 5G carriers. This can be done either with an LNB microstrip filter or mechanical waveguide filter or a combination of both. LNB filters are effective for mitigating light 5G interference that is off-boresight. To mitigate much stronger 5G interference that is closer to boresight, a waveguide filter is necessary to suppress the interference before it enters the LNB and passes through any nonlinear devices.

If you are a TV or Radio station and already have an orthomode feed system, then all you need to purchase is our waveguide post filter. You can use it with the conventional LNBs that your already own and it will likely mitigate your 5G interference without further action. Best of all, unlike our competitors, we sell the waveguide filter at a price point that won’t break the bank!

If you require the orthomode feed assembly, then we have two solutions:

  1. 5G Light Mitigation Feed System (Dual or Single)
  2. 5G Strong Mitigation Feed System (Dual or Single)

We also encourage backyard satellite TV enthusiast to upgrade to a commercial grade orthomode feed system if they are experiencing 5G interference. It is the best method for mitigating 5G interference and you can continue using your c-band satellite dish!

5G Anti-interference Consumer LNBFs Available

If you are experiencing 5G interference with your C-band antenna you can get your reception back with our new 5G Anti-interference Consumer Dual Output LNBF! Click here.

The passband for this LNBF is 3.8-4.2 GHz.

Please note that this LNBF works well if you are experiencing light interference on a few transponder over the satellite arc. If you are experiencing extremely heavy interference where almost every transponder is affected, you will need our commercial waveguide filter with sharp bandpass frequency cutoff response to solve your problem. Recommended for TV and Radio stations.

Some 8ft Mesh Polar Mount Antennas are Available

We have a few 8 foot mesh polar mount dishes available. They are the most recent model (2019). You can purchase the antenna by itself or the complete motorized kit. We also have buried poles, king posts and pyramid base poles for these antennas. If anyone is interested, you can purchase here

8ft Mesh Polar Mount Dish Only

8ft Mesh Polar Mount Dish with 36-inch Actuator, Controller, C/Ku LNBF (complete motorized kit)

Once these are gone there are no more due to the pandemic and supply chain disruptions, not to mention the weaker economy. 

We sold several hundred of these over the years to backyard enthusiasts and feed back was generally very good. This dish is small enough that you won’t get hassled by your neighbours, but large enough to lock almost every transponder over North America.

12ft Mesh Dish (Floor Model) Available at Discounted Price

Own a piece of TVRO history!

Our 12ft Mesh Polar Mount Dish floor model is for sale. The asking price is $1799 USD shipped anywhere in the continental USA or Canada. Perfect for that small TV/Radio station on a budget or the backyard enthusiast who wants a large dish without breaking the bank!

We used this dish to take pictures of the 12ft mesh dish models which were posted on our website, affiliate websites, Amazon, ebay, etc! The dish mount is brand new (unopened box). It is the latest model mount with dual screw declination, elevation bracket and thick gauge steel construction. The panels are from a 2017 production run, but we never changed anything in subsequent productions runs, except to drill multiple feed strut holes in the ribs. You can drill any additional feed strut holes yourself with a standard drill.

Now, we did perform some modifications to these panels:

1. We drilled two small holes in the mesh of one of the panels for passing the coax cable;

2. There were some additional small holes drilled in the lip of some of the panels for mounting an experimental dish shroud. They are very small and have since been painted over.

That’s it! Besides those two modifications, it is like brand new. It has never been exposed to the elements, there are no tears in the mesh and they are still shiny gloss black.

If anyone is interested, please send me an email ( and we will reply with a payment link. We also got buried poles, pyramid base poles and King posts available for this dish. Even NPRM for radio or TV stations that want to install on a roof. You can also motorize it with our 36-inch actuator and controller. Let us know if you need the extras so we can quote you.

Some 8ft Solid Dishes are Available

There were a few of those over sized 8 foot solid dishes at the back of the warehouse. I noticed them last week as we moved some other inventory. They are exactly the same as the ones we were selling since 2017 and are the most recent model, except they come with a black King post instead of the gray one. I can substitute the King post for a buried post or pyramid base if requested. All of the posts are gloss black. If anyone is interested, you can purchase here:

Tek2000 is Open for Business during the COVID-19 Pandemic

Tek2000 will continue to process and ship out online orders during the COVID-19 pandemic. We are committed to our customers during these extraordinary times like never before, but will also be implementing certain measures to slow down the spread of the virus in our community.

Effective immediately, only one employee will be permitted to work in any of our warehouses on any given day. Walk in or pickup orders have been suspended. We will only process and ship out online orders.

Shipping with the main carriers like Purolator, UPS and Fedex will only take place once a week, and that will usually be on Mondays. This means that regardless of when you place your order, it will ship out the following Monday. The only exception to this rule will be a large order from a TV station or commercial client. Please contact us and we will arrange for a truck delivery appointment that is convenient for you.

Please be aware that to mitigate the spread of the virus, carriers like Purolator, UPS and Fedex have informed us, until further notice, that they do not require a signature from you when they deliver. They will leave your packages on the front porch or other location that you can specify to us when you place your order.

We hope all our customers stay safe and this pandemic is over sooner rather than later and life gets back to normal.

Antenna Production Suspended: Limited Inventory

Due to the recent outbreak of the Corona Virus epidemic in China, we have been forced to suspend all production of our antennas. At this time, our supply chains in China have become disrupted and it is nearly impossible to obtain any raw materials or manufactured goods from that country.

We do not know when things will return to normal. Workers are not returning to factories. Ports are not shipping containers. The country is in complete lock down.

At this time we have limited inventory of 10′, 12′, 13.5′ and 15′ antennas. This inventory won’t last more than 1-2 months. We are out of stock on 6′ and 8′ antennas and have been for a while. Other products like controllers, actuators, feed horns and LNBs are in short supply too.

We contacted everyone who expressed an interest in purchasing our products in the last two weeks and let them know about the situation and reserved their orders. Now we are releasing a public statement so everyone knows about the pending shortages.

If you are a TV or Radio station manager and need a large antenna, please contact us and we will reserve it for you. If you are an amateur satellite enthusiast and were planning to install a C-band dish this spring, you may want to purchase your antenna sooner rather than later. If our web store indicates something is in stock, then we have it in our warehouse and you can order it immediately.

We hope the situation in China gets back to normal soon, but there is no guarantee of that happening. In the meantime, we are looking at other supply chain options, including domestic manufacturing of certain products.
