Earlier I mentioned the bad SRH805S Clone from China, that was no good in any kind. Yesterday I forced it open and wanted to share the pictures of the inside with you:

Device consists of a single coil aroud a PVC-stem

The coil is screwed into the SMA-f connector directly

The coil has a diameter od 9mm and a total of 7 turns. I'd really like to measure, if there is ANY resonant frequency, but I still can not afford the equipment. :/

Anyway: This antenna is no good on no VHF/UHF Ham Band in Germany ;).
