station antenna

The HF antenna's are dipoles for 10m/20m/40m all the antenna's are erected as shown in the photo. The 10m dipole is hanging from the curtian pole in the corner of the room and running along the skirting board. The 20m/40m antenna's run along the top of the wall and run down the wall at opposite ends and along the skirting board. The 40m dipole is almost like a folded dipole the space between the tips of the elements along the skirting board is around a 2.5 metres All the dipoles are made from 15A figure 8 Power cable.

The 20m/40m dipoles use the same feeder one half of the figure of 8 power cable is cut for 20m and the other for 40m. The SWR on the 10m dipole is virtually 1:1 across 28MHz and the SWR on the 20m/40m dipoles is < 1.5:1. I found the bends in the dioples shorted there length to around 65% of the calculated. The noise floor on 40m is at best S6 on my Flex1500 and around S7/8 on the TS2000 on all other bands above 40m it gets better on 10m its aroiund S2/3.

The antenna's are tuned against a set of 4 counterpoises to cover the bands from 10m to 40m The antennas can be used on all bands between 10m and 40m with the MFJ949E ATU.

For 2m I use a home brew 1/4 wave made from a wire coat hanger mounted on a sweet tin as shown in the photo. The length of the whip from the PL259 tip is 22 inches or 57cm.
