Antenna Suggestion

[garethiowc]

Hi all,

I'm after a suggestion for a good 433mhz antenna for my rflink.

My garden sensor is 25 meters away from the rf link and it can't be seen when in place.

This is my current antenna -

Antenna's are working on transmitting and receiving.

This is a good antenna for the RF link, but you need to improve/change /look at the antenna on the receiver side as well.

What are you using for the receiver side?

Also, can the transmitter "see" the receiver? How many walls or electricity cables are in between?
Then the position ( horizontal / vertical ) is influenced as well.

As you might have seen, in commercials they list 100 meters in open fields but 10 or less in a house.

Hope this helps you a little.
