Antenna Trap Losses and how to minimise the,

Antenna traps are widely used in ham radio antenna design. There is an insertion loss, but there is also an additional loss if the trap is not correctly tuned,

Wow! Who would have thought that to be a fact!! It is REALLY illogical! I started Hamming at 15 years of age, and now am 81, and NEVER heard that fact before!! I am CERTAINLY glad that I woke up this morning, to hear this INVALUABLE bit of information! Thank you SO VERY MUCH, PETER!! That fact alone saves a lot of EXCESSIVE power bills from wasted amplifier power!! LOL!! 73's K6PAM

Thanks Peter. I didn't know that...

[@watersstanton]

You are very welcome.

[@hoggif]

That was something new to me. Thanks!

[@johnforte3466]

What would be the effect of multiple traps such as on a triband beam. If amplifiers weren't used are no traped antennas better?

[@hamtek]

Very interesting, thanks! Do you have a link to the article that explains the theory behind this please?

[@watersstanton]

There is a link in the text below the video.

@@watersstanton Oh yes! Being silly, thank you.
