2G/3G/4G Combo Screw Mount Antenna with RG174 Cable (L-3MTR) + SMA (M) St. Connector

A 2G/3G/4G combo screw mount antenna is a type of antenna designed to support multiple generations of cellular technology, namely 2G (GSM), 3G (UMTS), and 4G (LTE). These antennas are typically used in applications where there's a need for reliable cellular communication across different generations of networks.

The "screw mount" aspect refers to how the antenna is installed; it typically involves screwing the antenna onto a suitable surface, such as the roof of a vehicle or a fixed structure. This type of mounting provides stability and durability, making it suitable for outdoor and rugged environments.

What is the difference between dual-antenna design walkie-talkie module SA618F30-DZ and SA618F30

SA618F30-DZ and SA618F30 are a high cost-effective, highly integrated, high-power full-duplex Walkie-talkie module. These modules are equipped with a high-speed microcontroller, codec, high-performance RF transceiver chip, and RF power amplifier, and provide a standard serial port for module communication. This enables the easy and quick configuration of module parameters and control over its transmission and reception functions. Users only need to connect audio amplifiers, microphones, and speakers to this module, and it can function as a small-sized intercom. Its simplified interface and extremely compact size allow for widespread applications and convenient integration into various handheld devices, enhancing the comprehensive performance of end products. These modules can be utilized in places such as full-duplex headset-style intercoms and handheld intercoms, including scenarios like working at heights or property security.headset intercoms and handheld intercoms can be evaluated in application areas, such as aerial work, voice security and other applications.

The similarities between the Walkie-talkie module SA618F30-DZ and SA618F30:

Frequency Range: 410-490 MHz (Customizable to 150-960MHz)

Up to 8 devices can transmit simultaneously (Unlimited for receiving)

Supports echo cancellation function

Push-to-talk and VOX dual intercom modes

Multi-level wireless relay

I2S digital audio + Analog audio

Line In + Mic input

Supports data transmission

Low-power consumption during sleep

Supports OTA and serial port upgrades

Open field transmission distance is 3-4 kilometers

High receiver sensitivity: -117 dBm

Differences between SA618F30-DZ and SA618F30

The major difference between SA618F30-DZ and SA618F30 is that SA618F30-DZ adopts the concept of a dual-antenna design. SA618F30-DZ builds upon the SA618F30 module by separating the transmitting and receiving antennas. Simultaneously, it exposes the TXEN pin externally, making it more convenient for customers to add an external RF power amplifier to increase the transmission power and thereby extend the communication range

SA618F30-DZ module size

SA618F30-DZ is a highly integrated, small size 1W high power full-duplex Walkie-talkie module. Its biggest feature is that the transmitting antenna and receiving antenna are separated, making it convenient for customers to add an additional radio frequency power amplifier. The SA618F30-DZ Walkie-talkie module supports 8 devices transmitting at the same time (receiving is not limited), and supports I2S digital audio + analog audio input. In addition, NiceRF provides differentiated customized services, and manufacturers are welcome to inquire.

Okay so I figure there's 2 ways to go about this:

1. Using a generic shock collar: most shock collars work on 433Mhz, which with the right antenna can be sent from a raspberry pi pico or zero (need a lot of processing power to analyze voice). Because of safety concerns the best place for the shock collar to be worn isn't around the neck, but you know what is perfect to wear around the neck? A throat microphone (sometimes called a whisper microphone or neck microphone) which detects the vibration of your vocal cords instead of the vibration of the air, meaning they're super sensitive. With a little fancy leatherworking you can make the throat microphone blend into the collar for everyone except the wearer who would feel it. From there all your need to do is mount the raspberry pi, attach a 433Mhz signal generator, attach the microphone, and slap some code in there that controls everything. Mods to the shock collar itself, and some off the shelf parts you can get from like Amazon.

Option 2: use a pishock or other IoT shock collar. Essentially the same but realistically not as practical but if you already have a pishock and don't know much about using an SDR to capture transmissions and recreate them, it's a good option. Setup for the voice detection is basically the same, just no 433Mhz transmitor needed. Microphone detects voice, rpi analyzes and desides shock or not based on whatever you set, and sends a request to the pishock Api to deliver a shock.

Both of these are also useful for.... Other sounds. Want the wearer to only bark? Easy. Want the wearer to have a very specific accent? Offload voice processing to a more powerful computer and use machine learning to detect the accent. Want even the slightest sound to deliver a shock? Scarily easy.

@worlds-smuttiest-epsilon is that enough about the mechanics? This is something I'm actively working on building so I've thought long and hard about it >:D

What if there was a collar for voice training where whenever you lost the girl voice it would shock you. As you get better at it it would slowly dial in on what is/isn’t acceptable

The kit comes with a pre-assembled FM radio module, an audio amplifier, a speaker, and a power supply. The pre-assembled FM radio module features an integrated circuit (IC) that can tune to FM frequencies between 88MHz and 108MHz. The module also includes an antenna that can receive FM signals from the airwaves. The audio amplifier can amplify the audio signal from the FM radio module, and the speaker can produce clear and crisp audio output. The power supply can provide power to all the components of the kit.

The Wireless Stereo FM Radio Kit is easy to assemble and requires no soldering. You can simply follow the step-by-step instructions provided with the kit to build your own wireless stereo FM radio. The kit is also very affordable, making it an ideal choice for beginners or anyone on a budget.

RF Wireless Module Pair (433MHZ)

The RF Wireless Module Pair (433MHZ) is a pair of wireless modules that can transmit and receive data wirelessly. The modules operate at a frequency of 433MHz, which is a commonly used frequency band for wireless communication. The modules are very small and can be easily integrated into any DIY project.

The RF Wireless Module Pair (433MHZ) works by using amplitude shift keying (ASK) modulation. The transmitter module sends data by varying the amplitude of the carrier wave, while the receiver module detects the variations in amplitude and converts them back into the original data signal. The modules have a range of up to 100 meters in an open area, making them suitable for a wide range of wireless communication applications.

HC-12

The HC-12 is a serial communication module that can provide wireless communication over a long distance. The module operates at a frequency range of 433MHz and can transmit data up to a distance of 1,800 meters in an open area. The HC-12 module can be easily integrated into any DIY project that requires long-range wireless communication.

The HC-12 module uses a frequency hopping spread spectrum (FHSS) modulation technique to provide reliable and secure wireless communication. The FHSS technique involves hopping between multiple frequencies in a random sequence, making it difficult for unauthorized users to intercept the data signal. The HC-12 module also supports a variety of baud rates, making it compatible with a wide range of microcontrollers.
