A homebrew G5RV (PVC pipe used for center insulator and mast)
| G5RV Size | Legs | Vert. radiator (300 ohm twin lead) |
| 10-40m | 26′-6″each | 14′-3″ |
| 10-80m | 51′ each | 29′-6″ |
| 10-160m | 101′-6″ each | 53′ |
Notes:
- 1. Use a minimum of 50 feet of coax (I prefer RG-8X) for 10-40 meter size and 100 feet of coax for other sizes.
- 2. You can “hardwire” all connections (solder and waterproof) or use 1:1 balun (CT) for twin lead to coax connection if concerned with TVI as I was operating from an apartment (or 8-10 turns of 6″ diameter on coax for homebrew choke may work for you). Spi-Ro Manufacturing makes neat baluns with screw terminals (www.spiromfg.com).

How did you arrive at lengths for twin lead and legs? Did velocity factor figure into your equation? de n4iyx
HI, WHAT ARE THE DIMENTIONS FOR THE G5RV IF I USE 450 OHM LADERLINE? THANKS.
Hola Simone: Agradeceré que publiques el diseño y comportamiento de una mini RG5V multibanda, debido a que no dispongo de mucho espacio en el techo de mi casa. Muchas Gracias. Saludos.
