German Commercial Log-Periodic Antenna for 28 to 144 MHz

Thanks to a comment left on the blog by a reader named Phil, I came across this German Log-Periodic antenna which covers 28 MHz to 144 MHz.

This antenna manufactured by Anjo-Antennen is designed to cover the 10m, 6m, 4m and 2m amateur radio bands.

Specs below...

Length mechanical: 3.38m
10m band V = 72 ° / H = 167 °
6m band V = 70 ° / H = 149 °
4m band V = 73 ° / H = 164 °
2m band V = 80 ° / H = 167 °

Comment... While this antenna is designed for the four amateur bands at 28 MHz, 50 MHz, 70 MHz and 144 MHz, it would also make an very good receive antenna for the low VHF bands. It should have similar gain and front to back figures for say 40 MHz, 60 MHz or even the broadcast band at 88 to 108 MHz.

Looking at the website, the VSWR at 40 MHz and 60 MHz looks as if it is in the region of 1:1.7

The product can be found on the company website at

They also make other models which cover different frequency ranges.

The LP045150S covers 45 MHz to 150 MHz.

The LP045500S covers 45 MHz to 500 MHz.

The LP049073S covers 49 MHz to 73 MHz.

Hi John

Just wanted to let you know about another LP covering Low VHF: model LP028150S by ANjo-Antennen, Germany (

This may be of interest to our European friends (continental shipping). I have seen his stand at European rallies, quite impressive with loads of antennas mounted on alu masts.

73, Phil

PS: I have no personal / commercial relationship with this company, just for info.
