Un double dipole 14-21 Mhz
Very simple to manufacture, it is cut for the bands 14 and 21 MHz

15 Element Wire Log-Periodic 7 MHz - 30MHz TITANEX DLPD-15
Feeding with just a single coax cable for all seven bands 50 hm Loss-free linear loading feeding on 10MHz, full-size rotary dipole on 7MHz
40-10 Meter Antennas
All three dipoles were fed from a single 1:1 balun
6 band windom anten 80-40-20-17-12-10m, TA1CD
Our antenna will serve us for a long time if we isolate these parts from the external environment with hot silicone or similar materials after soldering the connections in honey. We can use our antenna in all hf bands except 160m, 30m and 15m
A dipole portable
Configured as a dipole, the ATX whips appeared not to be long enough.A loaded dipole is more efficient if the loading coil is closer to the top of the antenna

Linear loaded short dipole 21Mhz For my 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
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
