Hi,


A while back I converted my F14 TX to be dual frequency with the addition of a Corona 2.4Ghz DIY kit, I detailed the build here:

This has worked really well until the aerial for the Corona unit broke, does anyone know exactly which screw on black aerial this system uses as I am tired of buying incompatible ones

Hi Alex,

Post of pic of the antenna socket - likely RP-SMA- is it male or female?

Does it look like this

if it is anything like their module for the futaba radios (see picture) then you need to get an "RP-SMA" style antenna... like the following:

Hi Guys,


Thanks for the replies, I will have a look after work tonight and see what the socket is like

Hi Alex

Just read the detail (see below) on the CoolComponents website - this could be a factor in the frustration  of getting a correct replacement- however both are available

The FCC is moving towards Part 15 compliance.
All this means is that all the SMA RF connectors are changing gender. Really annoying for those of us who need to mate an antenna to an RF device.

The FCC gender change was instituted to prevent home users from damaging RF equipment (think home WiFi) when screwing on an antenna.
If all antennas are female, there is no way to damage the center connector.

Hi Guys,


So checked the aerial socket and it looks like the Cool Components one for the win, will order one and find out! Can't wait to have my favourite TX back in action


Thanks for the help

Well I bought the new aerial and it broke on the first outing, not impressed, once I source an alternative I will try again

Alex,

I guess from your comments it was the qulaity of the product at fault and not the user (!)

I have several from Cool Components that have survived some years

Have a look on Amazon...quite a few different ones - this is just an example

Hi C-3PO,


Yep, I may be ham fisted but this was a quality issue 


Many thanks for the link, I will have a closer look tonight when I have the TX in front of me
