sleeve dipole variants

once i made a sleeve antenne with RG174 for 2m - it works. now i decided to use RG58. i startet with the 70cm version on the left. the right picture shows the electrical wiering. its a mid feed vertical dipole. the coil at the bottom acts as RF-isolator so that the feedline coax below the coil dont radiate RF -

test



2m sleeve-bazookaa

shows SWR with MFJ-269

SWR of the 2m version.
1:2 bandwith is 10 MHz

in this experiment i combined a sleeve antenna with a 1/4 wave bazooka element and it works.
