Linear loaded short dipole 21MHz
- Amateur radio activities on the hf bands i only have a 3.6 m wide balcony available for antennas, after some study i decided to experiment with a shortened dipole for the 15 m band
post 29 May 2026
Antenna 15m 21 MHz Links →
2 Eement. FOR 10-12-15MT
Poles are 5 mt length 21 mhz I use four bamboo poles for each element
3 Element Yagis Antennas for HF
Use the DK7ZB-match with 2x75-Ohm-coax for the 28-Ohm-Yagis and 2x50-Ohm-coax for the 12,5-Ohm-Yagis
Delta Quad
2 elements driven in phase inversion, single band for 15 m
