Last week I made a J-pole antenna for 2M. This antenna is made of 300 Ohm ladder-line I found in my junkbox. Yesterday evening I used the antenna indoors, hanging from the curtain rail, and could reach PI3AMF, a repeater in Amersfoort. A distance of 28 km. I used my FT817nd with 2,5 watts output.
This weekend I want to measure the swr with an external SWR meter.
The rest of this week I had no time for the hobby.
18:30 UTC. I saw that my swr meter is not suitable for 2m, stupid of me. Now I should just borrow one from a colleague in the neighborhood.

This is a tiny, digital only, HF transceiver that may be used with free
software like WSJT-X or JTDX. It is available in a version for the lower
HF band...

I made a ribbon cable J-Pole too. I still use it. While the SWR is obviously important, try comparing it against a quarter wave whip or other 2m antenna if you have one handy to see how much difference it makes.
