- G4CQM Homebrew VHF Yagi antennas
- Homebrew VHF Yagi 50MHz 144MHz 432MHz 1296MHz 2320MHz 6M 2M 70CM 23CM 13CM Yagis
[Hits: 5943 | Votes: 37 | Rating: 8.39] - X-Beam for 6m 2m and 70cm
- X-Beam antenna by K0EMT for 50 Mhz and VHF UHF bands
[Hits: 1026 | Votes: 1 | Rating: 1.00] - Dual band 6m/4m Yagi
- This antenna was optimized with the goal to minimize any changes in 6jxx6 impedance/lobes. The result is a 7 el on 70 MHz with a little loss of gain comparing with the other monobands of the same lenght.
