Simple J-Pole for the 2m band
To adjust the SWR you will have to "play" with the 40mm distance between the coax feed and the braid -- inner conductor connection. I could obtain a SWR of 1:1 at 145MHz. All together in my favourite material, PE tubing, with a simple tripod this makes my 2m standby aerial.
