• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

There's an article on the SWLing.com website reviewing the Bonito e-field antenna, the MA305

Brilliant hard-core DX with the USB-powered Bonito MegActive MA305 antenna | The SWLing Post

and as for the antenna itself...

Being an e-field antenna, you need to be in a real quiet area, able to put the antenna a good distance from the home (like a rural setting) to use this antenna effectively. Otherwise you may hear a lot more noise than signal.

I see to things that concern me about this antenna. First is its powered by USB and that can couple RFI from a computer into the antenna. I think computers and VLF/HF antennas should be separated as far as possible to avoid problems.

The second thing is the current consumption is only 10ma @ 5V, putting it at the low end of surviving in a high RF area and it probably overloads and creates IMD very easily. Higher performing active E-field antennas usually run from 12 to 24V and consume 50 to 100ma, which is needed to bias and run the larger transistors which will operate in high RF environments with no IMD.
