8 | We have seen great performance from the Procom '''MU 4-MM/CEL4''', which is a magnetic mount car antenna for the 410...430 MHz range: |

11 | The same antenna type is available for other sub-bands commonly used for tetra, e.g. 380-400 MHz (CEL5) |
||
12 | |||
13 | Antennas can be ordered from a variety of distributors such as e.g. [http://www.ukw-berichte.de/ ukw-berichte] (Part #P130000912) |
||
14 | |||
15 | Please note that the antenna ships without any cable. The magnetic mount has a FME socket, so you will likely want to |
||
16 | order some FME-to-FME cable (ukw-berichte part #20227) as well as a FME-to-SMA adapter (ukw-berichte part #00218) |

20 | There is a nice combination available from [http://www.dg0ve.de/ DG0VE]: A ~ 20dB LNA with a double-helix filter (10MHz band-width). It's called '''LNA 70-1''' and can be custom-ordered with e.g. a center frequency of 425 MHz: http://www.dg0ve.de/LNA70_1_2010_001.pdf |
