Good for HF, usable with UHF, very limited usable with VHF. The DC resistance of 48.8 Ohm remains usable up to 144 MHz, where the SWR is 1.06 At 440 MHz, the SWR then increases to 1.54, and at 900 MHz, the capacitive parasities provide then already for a SWR of 3.38 (see enclosed measuring graphic). Unfortunately, any labeling on the part is missing.

Gut für HF, brauchbar bei UHF, sehr eingeschränkt verwendbar bei VHF. Der DC-Widerstand von 48,8 Ohm bleibt bis 144 MHz brauchbar, wo das SWR 1,06 beträgt. Bei 440 MHz steigt das SWR dann aber schon auf 1,54 an, und bei 900 MHz sorgen die kapazitiven Parasitäten dann schon für ein SWR von 3,38 (siehe beiliegenden Messgrafik). Leider fehlt jegliche Beschriftung auf dem Teil.

They seem to be good quality (50 ohm +/-0.1 ohm) but are totally devoid of any branding or model number codes.
