High noise floor on hf.

Lowering the hf noise floor. Lowering the noise floor on hf with high quality coax. Some examples are the bono whip 20khz 300 mhz gigaactiv 9khz 3 ghz and the megaloop 9khz 200 mhz. Over on their blog they ve uploaded a post titled why even good antennas need good coax cable.

Carry high speed data signals using frequencies in the hf bands became a possibility there has been an attempt by some proponents of such systems to claim that the ambient background noise level on the hf band is already so high that this justifies high levels of broadband noise emissions. If i put the tuner into bypass mode i can usually improve the noise floor by an s unit or so on any band. If the noise level drops you can unplug everything switch on the mains supply at the breaker and start plugging things in to see what is causing the noise. Leave a comment.

That said background noise can be managed by controlling the source of the noise or even removed if using an hf transceiver with noise reduction technology like the barrett 4050 hf sdr. Depending on the severity of the problem this can make clear communications difficult. Bonito is a company that sells various products such as their own small active antennas.
