The Homebase 10 halo antenna

Antenna 10m 28 Mhz Links

35



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
