    Somewhere on the net I found a neck spacer of 70 cm.

    Unfortunately, I can no longer find them. Can someone help me??

    I recommend DK7ZB, or DL6WU.

    A simpler antenna for 70 cm? Clearly, the antenna with a radiator impedance of 50ohm, the design of any transformer does not balance its benefit for small antennas.

    I recommend DK7ZB in 50ohm version or DL7KM. S “littleness” antennas, but I wouldn't overdo it 😆

    7km long is too big for me.

    dk7zb in the 50-ohm version, I somehow didn't get it, you don't have a link?

    Thanks for the link, but I came across your site a long time ago and these antennas are very long and profitable ,since in our geographical areas, FM has degraded to local chatter (I have the impression that in one discussion about PP, it is possible to find the opinion that FM connections should not be included in the connection to increase the class) it is pointless for me to use such a powerful antenna. I only have FM on 70cm “TRX” (in quotation marks because it still doesn't look like TRX) and I'm not going to change it.

    ``your opinion'' is certainly true and I will not refute it in any way.

    maybe in time you will understand…

    ;-))))) of course, but thank you anyway.

    besides, I won't have a place to put an antenna bigger than my neck for a long time, so I'm looking for a small one like this. and I would also like to use it on a portable later

    even half of this is enough

    I used it to make a 70cm neckerchief, what came under my belt and the results were not bad. I recommend grabbing yagimax somewhere, rewrite the KRCk to 2m and reduce in proportion. There is a function for that. I kind of made it up then. Coax loop adjustment. If I haven't already thrown the invention away (I did a bigger yagina), it was really an emergency, I will measure it…unless I forget…
