Hi Derek,

Recieved the Long range external antenna from the shop and I was wondering about the best way of 'tweaking' the board to accomodate the connector, alternatively I would prefer to mount the connector to the shell of the Livebox but in doing so I would need to extend the connection from the RF board to the socket - is this advisable?

Thanks

David

RF Pigtail

Hi David,

The connector that is supplied with the external antenna is designed to fit directly onto the RF module board (I simply snipped off three of the four mounting pegs and enlarged the 'ant' connection hole on the PCB to fit the middle pin on the RF connector. However,  i run my HAH 'case off'. This style of fitting isn't ideal if you intend to close the case again.

What you need is a 'pigtail' conncetor. This comes pre-wired and heatshrunk (at the SMA end) and will mount onto a suitably placed hole in the side of the HAH enclosure. Just ensure that there is both a ground connection and the 'ant' connection on the pigtail.

So, I'll create another item on the shop for this 'pigtail' and will send one on to you by way of thanks for pointing this out.

Thanks Derek,

This looks just the job.

Re the ground connection - looking at the picture of the RF Transmitter Module at the top left is GND - I presume this would be the location to connect the ground (shield) wire?

Yes, this Gnd point is just fine. You might have to strip back the pigtail shield wire a bit ... I'll pop in a short length of heatshrink to help with attaching this without any shorting.

Derek.

Hi Derek, Thanks for the pigtail - it's now installed. However I now notice that if I select more than one item from the RF control page to switch on or off only the first item in the list is switched - I would think this is an issue with the build (currently on 300) and something for Brett to comment on, otherwise all seems fine and selecting one item at a time works OK. Happy New Year David

Nice work

The pigtail part looks to be a good fit. If it's OK with you, I'll include your image on the wiki as an exemplar of how to fit the antenna connector.

I'll chat with Brett re the 'more than one item' issue that you are seeing.

Cheers,
Derek.
