Very powerful wave maker, highly recommend.

2023年2月15日 · The best part of the 3/8-wave antenna is that you can easily multi-band it with 1/4-wave "stubs" connected at the corresponding 1/8-wave-up point on the radiator. There isn't a lot of interaction unless the bands are close. For VHF, one could make a nice 50, 146, 222 and 440 multiband antenna for very low cost. Or 10m/6m.

Kit delivers 80m as a loaded quarter wave with 30m as a colinear and full quarter wave on 40m and up. 12m and 10m get 3/4 wave elements. Shipped in 2 x boxes (See components page).

2016年11月30日 · For a 30m quarter wave vertical the sums are: 300/10.1MHz = 29.7m/four = 7.42m or about 7.054m if using PVC-coated wire. Once optimised expect to see an SWR of …

The massive EXTREN® channel insulator supporting the 6063 drawn aluminum antenna radiator has over twice the tensile and flexural strength of competitive nylon plastic materials, and is superior for its RF handling characteristics. Another key to performance in any quarter wave vertical is a good ground radial system.

2021年4月15日 · António Laureano claims to have ridden the biggest wave ever at Praia do Norte in Nazaré, Portugal. The first measurement indicates a 101.4-foot (30.9 meters) wave.
