10 meter eh antenna
Version of the EH antenna using the L+L type matching network. Included in the assembly is a tuned trap which is effective in inhibiting out of balance current on the coax feeder and eliminating interaction between the feeder and the antenna tuning

Antenna 10m 28 Mhz Links →
2-Element parasitic Yagis 10m-30m
No other antenna has a better relation between gain and expense than the 2-Element-Yagi. One element additional to the dipole will give you 4dB gain
10 meter eh antenna
The antenna has the same basic circuit arrangement as the 20 and 40 metre
2 Element Cubical Quad
My antenna can be taken apart and is therefore well suited for the weekend in the garden or for the field day
10m 3 element yagi
Very short boom (3,00m), for 28,0-28,8MHz lightweight construction possible

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
