Ik kwam dit nog tegen op het Internet. Gaat over hoe je makkelijk een goede 433mhz antenne kan maken. Kan misschien nuttig zijn voor een ieder hier. Ik heb het zelf nog niet geprobeerd.

Bedankt voor de tip.
Je weet zeker dat dit echt goed werkt? Heb namelijk eerder een discussie voorbij zien komen over antenne's en antennelengtes e.d.
Meer mensen die deze antenne in gebruik hebben?
Snap het pdfje overigens niet helemaal.Hij heeft het over verschillende diameters draad, installatiedraad zwart maar als je kijkt naar de foto's is het dun koperdraad.Wat is jullie ervaring?

Ik heb er eentje gemaakt, maar ben niet ondersteboven. Hij werkt wel hoor, maar niks beter dan mijn gebruikelijke antenne: een stukje zwart elektrakabel van net geen 17cm.
Gewoon van dat zwarte montagedraad dat je bij 230V installaties gebruikt voor een geschakelde ader.
Is lekker stug, maar ook weer niet TE stug, en het kost bijna niks.

Bedankt,
Dan hou ik het eerst maar bij mijn cat6 upt kabel kern. Is net even een paar keer dunner maar heb geen problemen met bereik / ontvangst. Zolder -> 2x betonnen verdiepingsvloer -> Woonkamer.
Iedere minuut worden er twee userevents verzonden, van deze userevents zijn er drie niet aankomen afgelopen 6 dagen. Alleszins acceptabel dus.
