Arduino Uno R3 rev3 CH340 clone atmega328 - no cable usb

 

Arduino Uno R3 rev3 CH340 clone atmega328 - no cable usb - Arduino uno without a USB cable so that the price is cheaper, you can use a regular printer cable. Arduino uno available in SMD version 
This is the clone version, but don't get me wrong, clone doesn't mean fake
The difference is only in the usb to serial converter using the CH340 to replace the FT232RL

Log Periodic Outdoor Antenna / Periodic Antenna

 

Log Periodic Outdoor Antenna / Periodic Antenna - Log Periodic Antenna is widely used as a singal amplifier outdoor antenna because this type of antenna has a wide frequency limit (multi-frequency).

Unlike ordinary yagi antennas which can only work on a single frequency.

This antenna has a wide frequency (Wide Band) 800 MHz to 2600 Mhz, especially on LTE / 4G, 3G / 2G, and CDMA networks.

But traditional Yagi Antenna if for GSM only GSM In certain areas conditions can improve coverage characteristics and maximize modem connections. This Log Periodic Antenna is designed to be waterproof  with UV protection so it is very suitable for outdoor weather conditions.

Bracket that can be adjusted tilt angle, Mounting / Pipe clamps for poles diameter 3.5cm to 5cm, Installation guide and original modem pigtail 

(according to modem type). Pigtail modem can be replaced, you can buy it separately when you have a modem with another type.
