Hello,

Thanks for the photos. What receiver are you using for HF, how is the antenna connected to it (directly or with a balun) ?
What sort of distance can you receive ?

Thanks for your help.

I used 450 ohm latter line to a matching transformer, not a balun , a transformer isolates the antenna from the the receiver .
The transformer is 450 ohms to 75 ohms . I am using the HF+. Now for distance with propagation half way around the big blue ball .

Hello,

So ladder line + transformer is better than normal wire + balun ?
How does the RTL-SDR "Portable Antenna Set with 7M Long Wire and Telescopic Whip" perform in HF ? Does "Matching SMA Adapter" mean that there's some sort of balun or adapter in the sma connexion ?

Thanks again for your help,

James
