本人想做一个V型天线，但是它只能在一个波段上使用，所以有一个~~不切实际的~~想法，在U段的天线上加个头，需要时就再插两根铜线上去，变成V段的… 这个想法可行吗…

可以是可以，UV 段做 V 型天线干嘛，J型不好吗

@"BG7RCA"#p48185 要不你干脆买个看电视的羊角天线来改一下线，要U段就拉到U段长度，要V段就拉到V段长度，不用就收起来。

你可能需要这个。。。 [upl-image-preview uuid=29e0331d-b62c-4740-bcb0-e2032425da80 url=https://storage.hamcq.cn/2024-12-31/1735647648-150943-1e43d5d25719f0358bc0812c039b97e.jpg alt={TEXT?}]

How to combine a U-shaped and V-shaped antenna with a V-shape.

BG7RCA

I want to build a V-shaped antenna, but it can only be used on one frequency band, so I need~~Unrealistic~~The idea is to add a header at the top of the U-shaped section, and then insert two more copper wires when needed, transforming it into a V-shaped configuration.
Is this idea feasible?

BG7RCA Or, you could simply buy a TV antenna with a U-shaped or V-shaped connector and replace the existing cable. If you need a U-shaped connector, just cut it to the appropriate length. If you need a V-shaped connector, cut it to the appropriate length. If you don't need one, just store it away.

Yes, it's possible. What's the purpose of using a V-shaped antenna in the UV band? Wouldn't a J-shaped antenna be better?

Use a whip antenna.

Do I need to use a null terminator?
