Best Cables for Bobcat Miner 300 in 2023

In this article, we’ll outline the top three cables for using with the Bobcat Miner 300‘s high gain external antenna and N-Female connector.

We frequently receive the following inquiry: What cable should I use to attach a high gain external antenna to my Bobcat Miner 300 that has an N-Female connector, such as the ROSA-902-5-SNF or ROSA-902-8-SNF? Best Antenna for Bobcat Miner 300

There are two options for this:

Option 1: If installing inside, in a covered area (like a balcony), or if the likelihood of lightning striking your antenna is low, you can connect the antenna directly to the Miner.

Option 2: You want to utilize a lightning arrestor between your antenna and your Miner if you have any concerns about lightning striking your antenna (a strike will definitely destroy your Miner)

For Option # 1

For lengths up to 55 feet, use cable type PT240; for lengths greater than 55 feet, use cable type PT400. Next, decide on the cable length that is ideal for your installation. Connectors #1 and #2 should be of type RSM (RP-SMA Male) and SNM (Standard N Male), respectively, to connect to the miner and antenna, respectively. Check your selections carefully because cables are NCNR (non-cancellable & non-returnable).

For Option 2

If you want to add a lightning arrestor, you should start by getting one that is UL-rated.

Choose cable type PT240 and the proper cable length for your installation. You’ll need a short cable to connect the Miner to the lightning arrestor (between 5 and 15 feet). Connector # 1 should be type RSM (RP-SMA Male) which connects to the Miner and Connector # 2 should be SNM (Standard N Male) connects to the lightning arrestor. The second cable will connect the antenna to the lightning arrestor. For lengths up to 55 feet, select cable type PT240; for lengths over 55 feet, select cable type PT400; finally, select the cable length necessary for your installation. Lightning arrestor Connector # 1 should be of type SNM (Standard N Male) and antenna Connector # 2 should also be of type SNM (Standard N Male).

An N-Type male connector should be on the other end of the cable, which connects to the majority of standard antennas because they have a female slot, in order to connect the Bobcat Miner 300 and Antenna.

LMR-400 SMA MALE – RP SMA MALE

The Power Output rating of Hotspot equipment was previously higher in Europe. It has never been more crucial to use LMR-400 Cable assemblies as the ideal low loss interconnect because of the new output power restriction in Europe.

Previously, “RG” type coaxial The Helium Devices and antennas were connected with cables. Due to their extremely high loss characteristics and propensity to increase their attenuation over time, RG cables are currently a very undesirable option, which negatively affects the hotspot’s coverage and range.

Data Alliance Flat RP-SMA Antenna Cable

Flat Antenna Cables pass under a window so that you can set your Helium miner outside your window, for much better range. Loss from the antenna is almost 0 dB.

• To fit under a window or door, the cable flattens. They have weatherproof flat antenna cables throughout.
• The length of cable is from end of connector to end of connector
• Connectors: one is male & one is female
  • The following versions have RP-SMA Female on one end and RP-SMA Male right-angle on the other: 10-inch, 18-inch, 24-inch, and 30-inch. The seven-inch version has straight (not right angle) connectors on both ends.

COAX 400 Cable Low Loss Cable N TYPE MALE to RP-SMA MALE

Reduce interference with this COAX 400 cable, double shielded to reduce interference and reduce loss over long distances between transmitting LoRa Antenna and Bobcatminer 300 – thus increasing your coverage, range and rewards.

Setting Up An External LoRa Antenna Outdoors

Helium mining equipment can be indoor or outdoor in design, but an outdoor LoRa antenna is beneficial for both. Outdoor antennas are already incorporated into the design of outdoor helium miners with weatherproof, ruggedized enclosures. For indoor Helium gateways, an outdoor antenna must be connected to the miner via an antenna cable and then fastened to the miner’s female RP-SMA connector. The LoRa antenna can be positioned for maximum visibility while the miner is inside thanks to the antenna cable.

Tips for Bobcat Miner 300 Antenna Placement and DBI Selection – to Increase Witnesses

Transferring an antenna cable from a miner inside to an antenna outside.

Use a Flat Antenna Cable to pass the cable under the window, to position the antenna outdoors for much better range:

Running coax through to an outdoor antenna can be challenging. The cable is typically passed through a window or door if drilling through a wall is not possible. A standard coaxial cable, on the other hand, will be harmed by the closing of a door or window because the insulation and shielding will be disrupted, leading to a failure.

Flat antenna cables from Data Alliance can safely pass through a window or door frame. These cables are also known as:

• Flat coaxial cable couplers
• Window entry cables
• Window jumpers
• Window pass-through cables
• RF jumper adapter

This flat antenna cable is specially made so that it can be covered by a door or window without losing signal strength. The flattened length of coax is terminated by two RF connectors. Flat coax has a thin profile and suffers from minimal signal attenuation. A connecting length of micro-coax that is shielded by copper beads is contained within the flat coax. Most window jumpers have an adhesive strip to hold the coax in place in the window or door frame.

Without drilling or significant signal loss, a flat coaxial cable is the perfect way to connect an indoor helium miner to an outdoor LoRa antenna.

Installation of Flat Coax for Your Helium Miner is Simple.

The door or window is opened, and the flat coax is inserted into the frame and secured there with its adhesive strip. The window or door can then be shut over the flat coax. Antenna cable can then be run from one end of the flat coax to the antenna and from the flat coax to the Helium miner.

Attachment of a High-gain External LoRa Antenna is Key to Boosting Bobcat Miner 300 Earnings

Helium Network Token (HNT) earning by Bobcat Miner 300 is dependent on the visibility and performance of a gateway in:

• transferring IoT data from client devices
• proof of coverage (PoC) challenges
• PoC witnessing

By choosing an external LoRa antenna that can be connected to a miner to increase its coverage and efficiency, participating gateways in The People’s Network can increase their cryptocurrency earnings.

Like WiFi routers, most indoor and outdoor Helium miners are sold with a detachable omnidirectional LoRa antenna.

• This is typically connected using a female RP-SMA connector on indoor helium miners.
• The antenna connector on outside helium miners is frequently a Type N connector.

An antenna with better qualities for a particular setup or location can be installed in its place. 3 dBi Popular replacements include LoRa antennas, which can be fastened to the miner directly or via an antenna cable. These antennas come in 5.8 dBi, 8 dBi, and 10 dBi versions. Outdoor antennas can also be used in place of indoor LoRa antennas.

The best coverage for your Bobcat Miner 300 can be achieved by positioning an external LoRa antenna.

Hotspot placement is critical to optimizing earnings from the Helium network. A hotspot will make more money if it adds value. 4 key factors determine the optimum setup for a Helium miner:

1. Hotspot density: Because Helium miners not only earn from transferring IoT data but also from participating in PoC challenges, the location of the miner needs to ideally be amongst other miners where these challenges can take place.
2. The position of the antenna should increase the range coverage of the helium miner, which is best achieved by placing it outside the window or outdoors. Walls and glass will diminish the LoRa signal. The antenna should also be mounted as high up as possible with a clear view. The LoRa antenna’s height can be increased by 1 meter, which can significantly impact the helium miner’s profits.
3. The Rx power of the antenna is more significant than its Tx power when describing its characteristics. Performance can be improved by increasing gain, but if the gain is too high, the hotspot may become invalid. Pro Helium miners use optimally positioned outdoor antennas with a gain of between 5 and 8 dBi.
4. Connectors and cables: Antenna cables should be high-quality well-shielded coax that is kept as short as possible to prevent losses along the line. Profitability will also suffer from improper connector attachment or the use of numerous adapters.
