Scanner antenna issues

Postby jamieblatant » Mon Jun 18, 2018 9:26 pm

Hi all

Been out the game for ages, but now I have my man cave up and running i have dug out my scanner and am getting back in to the hobby as well as ham TX, ing

First issue the cable on my moonraker skyscanner antenna has snapped at the mount , questions are

Can I get a new mount I can solder the cable too


Can I crimp lugs to the end and connect to the base and anyenna ? Or will it get interference?

The video industry crimp instead of soldering up to high data rates - 12G video is demanding. The caveats are proper connectors, proper conductors and proper tooling to do it. Crimping via non continuous impedance electrical splices is not good - they can be very lossy. I suppose with all the variables - I might try crimping, but suspect I'd prefer to solder.

As for getting spare parts for old antennas? I somehow doubt it.

You do not say how old your antenna is, but coax cable deterioates with age, so the possability is that your coax is no longer doing what it should anyhow.
Moonraker has a poor reputation for build quality. So & I am assuming your moonraker is an indoor antenna, with pre-fitted coax. Replacing the coax, if the antenna interior is of sufficent quility to allow it, is no bad thing & it will not matter about appearence, as long as the joints are good, indoors. As water ingress, is not an issue indoors.
A new antenna need not cost a fortune. For example the Spectrum Communications Nomad antenna, including postage is only £22 & is plug & play. Just hang it in a window or the loft. Or even tape it to a post outside.
Height counts with scanner antenna.

thanks all its this antenna

it been a good little antenna and has done what i have wanted it to do its still in really good condition but the cable as been bent a lot were it leaves the insulated mount between the base and the antenna its self the cable is also in good condition

i have tested it out and the insulator has cont unity of the screen to the metal base and the centre core to the antenna itself

the insulator has a 10 mm thread in the top and a 8 mm in the bottom i have insulators like ths at work can i just use on of them i assume there is nothing specalised with regard to the length or the build its simply an insulator ?

thanks ill be getting one of those antennas for my loft
