<\/i><\/i><\/span>Shipping<\/span><\/a><\/h4><\/div>
\n

Which items are included in my scope of delivery?<\/strong>
\nOn each product page there is a section titled \u201cScope of Delivery\u201d. Only the parts listed there are included.<\/p>\n

What does express shipping mean?<\/strong>
\nExpress shipping means that your order will be transported faster and more reliably on the shipping route. Nevertheless, our statement \u201cready for dispatch in x working days\u201d also applies to express shipments.<\/p>\n

Do I need to pay import tax or duty in my country?<\/strong>
\nWe ship from the European Union, so recipients in the EU should not have to pay any taxes or duties. Customers outside the EU may be subject to taxes or duties depending on their location.<\/p>\n

How do I know if my order has shipped?<\/strong>
\nYou will receive an automatic email notification either from DHL Paket or from Mail Boxes etc. to the email address you have provided when the order is dispatched.<\/p>\n

Why didn’t I get an order confirmation?<\/strong>
\nPlease check your inbox and spam folder for the email address you provided. Please check your contact details in your profile again.<\/p>\n

Do you also ship to the USA?<\/strong>
\nYes.<\/p>\n

To which countries can I have my order shipped?<\/strong>
\nSee the Payment & Shipping<\/a> page for a list of countries we do not<\/b> ship to. Delivery to all other countries is possible.<\/p>\n

<\/i><\/i><\/span>FLARM BOOSTER<\/span><\/a><\/h4><\/div>
\n

When will the FLARM BOOSTER come in an outdoor housing with N connectors?
\n<\/strong>It is expected for the end of June 2022.<\/p>\n

What is the best setup?<\/strong>
\nThe \u201cbest setup\u201d is highly dependent on the installation location. We cannot provide any special guidance on getting the best setup in general.<\/p>\n

Does the FLARM BOOSTER work with my Miner?<\/strong>
\nSince there is a high number of miners and antennas on the market we rely on your understanding that we cannot test every combination.<\/p>\n

When shall I use the 10dB version and when the 17dB version?<\/strong>
\nThis question is hard to answer and we tend to say: If you connect only one miner directly behind the FLARM BOOSTER, mostly with some meters of cable in between, the 10dB version is fine for you. Just if you intend to connect multiple miners via a splitter, the 17dB version may be the better option.<\/p>\n

There is a 915 MHz symbol on the FLARM BOOSTER. Does it work in the U.S. and other 915 MHz areas?<\/strong>
\nNo, it doesn\u2019t work. Currently we don\u2019t have a version of the FLARM BOOSTER for any other bands than 868 MHz. To check which frequency band is used in your region, please refer to the following linkhttps:\/\/docs.helium.com\/lorawan-on-helium\/frequency-plans\/#frequency-plans-by-country<\/a> .<\/p>\n

How do I connect the FLARM BOOSTER with my antenna?<\/strong>
\nPlease refer to our Helium Setup Guide<\/a> .<\/p>\n

What does 5V-12V and 70mA mean? Where can I find a power supply with 5V-12V and 70mA?<\/strong>
\nIt means you can use any power supply that outputs a voltage between 5V and 12V, which is capable of supplying a minimum current of 70mA or 0.07A. A power supply with 5V and 1A will do just as well as one that is capable of 12V and 100mA. You can use any power supply with a voltage between 5V and 12V and any current with at least 70mA (0.07A).<\/p>\n

The FLARM BOOSTER can be supplied with 5V-15V. Will its performance change if supplied with higher voltage?<\/strong>
\nNo, it will not change performance. It\u2019s equipped with an internal voltage regulator.<\/p>\n

What are the red and black wires for?<\/strong>
\nWhen feeding DC directly and not using our BIAS TEE connect the plus to the red wire and the minus to the black one.<\/p>\n

If I supply the FLARM BOOSTER with a BIAS TEE, do I need to supply it via the red and black wire in parallel?<\/strong>
\nNo, you don\u2019t. The supplies can be used alternatively.<\/p>\n

Can I get personal assistance\/support in building my system?
\n<\/strong>We offer you a fee-based personal consultation on an hourly basis. We offer you a fee-based personal consultation on an hourly basis. For an individual offer, please contact us at support@jetvision.de<\/a> .<\/p>\n

Is the FLARM BOOSTER batch date the shipping date or the delivery date?
\n<\/strong>The date is the non-binding shipping date. We make every effort to comply with this and inform our customers if it is apparent in advance that this will be delayed.
\n<\/strong><\/p>\n

What do the LEDs mean and how can I tell if the FLARM BOOSTER is working?
\n<\/strong>If the FLARM BOOSTER is properly powered, then the green LED should light up. When used for FLARM, the red LED flashes every second. When used for Helium-Mining, the red LED only lights up very rarely \u2013 only when a beacon is sent out.<\/p>\n

My FLARM BOOSTER is broken, what shall I do?
\n<\/strong>Please see the section of this FAQ: \u201cDefect FLARM BOOSTER\u201d.<\/p>\n

Will you repair my FLARM BOOSTER?
\n<\/strong>Repairs are possible. Our repair fee is EUR 30 plus shipping. In this case please contact shipping@jetvision.de <\/a>. If the repair should require more effort, you will be contacted by us.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>BIAS TEE<\/span><\/a><\/h4><\/div>
\n

How do I mount the BIAS TEE?
\n<\/strong>The BIAS TEE must be mounted between miner and FLARM BOOSTER, not between FLARM BOOSTER and antenna. The coax cable towards the FLARM BOOSTER must be connected to the side labeled with \u201cRF & DC\u201d, the coax cable towards the miner to the side labeled with \u201cRF\u201d. Please refer to our Helium Setup Guide<\/a> .<\/p>\n

The BIAS TEE is limited to 250mA, but I want to use a more powerful power supply, for example 1A (1000mA). Will that break the BIAS TEE?<\/strong>
\nIt will not break the BIAS TEE. The FLARM BOOSTER on the other side of the coax cable will only draw 70mA, which it is specified for.<\/p>\n

Will the BIAS TEE break if I supply it with 12V?<\/strong>
\nNo, the BIAS TEE will work with 12V nicely.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Cavity Filter<\/span><\/a><\/h4><\/div>
\n

When do I need a Cavity Filter?<\/strong>
\nWhenever you have GSM, Mobile Phone, LTE or other base stations in the neighborhood, a radio transmitter or any other equivalent station, you should use a cavity filter directly after the antenna and before the FLARM BOOSTER.<\/p>\n

Does the jetvision Cavity Filter need a surge protector?<\/strong>
\nThere is no need for a surge protector. Besides its excellent low attenuation the filter is also designed to provide a massive DC short in order to discharge any lightning and static electricity to ground.<\/p>\n

How can I differentiate between a good and a bad cavity filter?<\/strong>
\nA good cavity filter always shows attenuation values below 0.8dB. Bad cavity filters or SAW filters will be at 3dB or worse. Not least, SAW filters are sensitive against lightning and static electricity, so you risk their destruction when using it in an unprotected antenna cable.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Defect FLARM BOOSTER<\/span><\/a><\/h4><\/div>
\n

What can I do if my FLARM BOOSTER is broken or is not working as expected?<\/strong>
\nPlease answer these questions and contact support@jetvision.de<\/a> .<\/p>\n

    \n
  1. Which miner\/hotspot are you using?<\/li>\n
  2. Are you using a filter? Which filter and where is it connected?<\/li>\n
  3. Is the green LED on during operation?<\/li>\n
  4. How long did you operate the FLARM BOOSTER in your system until you have noticed that it does not work?<\/li>\n
  5. Did you ensure that the connector labeled \u201cFLARM\u201d is towards your miner and the one labeled \u201cAntenna\u201d is towards your antenna?<\/li>\n
  6. If using the BIAS TEE: The BIAS TEE must be mounted between the miner and the FLARM BOOSTER, not<\/b> between the FLARM BOOSTER and the antenna.<\/li>\n
  7. Are you aware not to mix standard SMA and RP-SMA connectors? See here<\/a> .
    \n– RP-SMA-female and SMA-male only fit with high force It might break the connector and due to that interrupt the signal path.
    \n– SMA-female and RP-SMA-male fit into each other easily, but may cause a open circuit for the signal.<\/li>\n
  8. Please give us a block diagram of the components and cables that you are using.
    \nNote:<\/b> Do not forget the power supply of the miner and FLARM BOOSTER.<\/li>\n
  9. Are there any GSM, LTE or other base stations in the neighborhood?<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1153","page","type-page","status-publish","hentry"],"yoast_head":"\nFAQ -
