FAQ:

Q: How big is the cable for a Yagi 433mhz antenna?

A: The Antenna Cable is 300mm long. It comes with a cable adaptor that will directly connect to Our 433MHz LoRa board using an JK-IPEX connector. Mounting Clamps are also included.

Q: How much gain does a 433 MHz antenna have?

A: Simple Yagi designs follow long established “half wave dipole” techniques, often using imaginative hardware – this “Cotanga” ( coat hanger !) based 433 MHz design has previously shown itself a good performer, offering perhaps 6dB ( = range doubling) gain over an isotropic antenna.

Q: Is the Dorji transmitter compatible with 433 MHz?

A: The Dorji receiver bandwidth (quoted as 200kHz) is wide enough to accept signals not exactly on the nominal 433.920 MHz, but was found selective enough to ignore nearby high power UHF CB transmissions around ~470 MHz. Classic 433 MHz ASK receiver modules are often very influenced by out of band signals.

Q: What kind of transmitter was used for 433 MHz?

A: An effective receiver was made by “persuading” a ~US$4 Dorji 433 MHz ASK (Amplitude Shift Keying) data module into analogue signal reception,perhaps from a companion PICAXE driven tone transmitter.
