I’ll also repeat the advice of the review from the UK as well, open the remote if it’s the 433MHz model, remove the top 11 coils of the antenna and stretch it back to its original length, so it’s a true 1/4 wave antenna. And the gain for the receiver station & relay switch will improve greatly. I haven’t been able to test beyond 300 meters, but so far, the relays all activate. A 443MHz 1/4 wave base antenna would be nice too, but it would be easy enough to replace for a dollar or two, or just clip a bit off it as well. And it works just fine as-is already. If the mag-mount antenna is stuck to something acting as a good ground plane, it should work fine for most wood or masonry buildings, or outdoor yard distances up to a few acres in size. I can’t say it’s “perfect” but it definitely can’t be beat for the price! 100% satisfied, five-stars, even “as-is.” And if you’re buying this, you probably have the skills to modify it if needed.

Das Preis-Leistungs-Verhältnis ist auf jeden Fall in Ordnung. Auch wenn die mitgelieferte Magnetfussantenne eigentlich keine 70cm-Antenne sein kann, ist die Reichweite völlig ausreichend. Ich habe nur bis 150m getestet, es wäre aber sicherlich noch einiges mehr drin.
