Tellstick with an antenna connector

Post by danardf » Thu Jan 18, 2018 11:08 am

Hi.
You could imagine the possibility to make a device with a antenna connector to put this antenna :

Just an idea like that. :)

I have that (Aurel) antenna but connected to my home made receiver and it is really great, I pick up signals from the surrounding several hundred meters from my house. To use it for transmission, I think it is not allowed but would of course improve very much

The key here is to provide a device with a suitable connector like SMA. There are cheap BNC to SMA adaptors available that could be used to connect the above antenna in such case

I have connected my TellStick to that antenna using an SMB to BNC adapter.

What did you think about the result? Was it better?

About my problem, it's better, but it's not perfect.
I won 2 or 3 meters, that's all.
I've not the same result between Linux and Windows. It's funny. :lol:
I've 2 receptors which work fine but the 2 others doesn't work on Linux.
If I try to use it on Windows, it's good.

Only pity is that a smb to bnc cost approx 4 times more than a sma to bnc... (~200SEK instead of ~50)

Much better :shock: my pre-release TellStick Duo can now pick up signals at approximately the same distance as my wlan.

Wow, did it improve that much???

My Tellstick Duo is only receiving at a radius of 5-6 metres with the original antenna. I will order an adapter from Elfa and connect my Aurel antenna then to measure the difference.

Did you get the same proportional improvements on transmissions as well?

I got almost the same result as you (up to 8 metres with the original antenna) using a standard Nexa transmitter, but had no problem receiving signals from all rooms in my house made by wood when I replaced the original antenna with the Aurel.

Have not tested how much the transmission is improved, I used an old TellStick with a wire antenna (modified by Telldus) connected to a laptop when I compared the range with my wlan.
