Several replies to my inquiry on having a closed 80 meter inverted delta loop inside a 160 meter delta loop brought me some nice replies. So I decided to build one for 18Mhz and 24Mhz with the feed g
The 18/24 is not a good analogy, because those bands are not octave spaced. My modelling indicated that you need to open up the lower frequency antenna at two places, 180 degrees opposed, in order fo
Hi, Herb Something you might consider is feeding the paralleled loops via a 4:1 current balun. I used this very successfully on a 2 el 5-band quad (my own design) fed with RG-213 through a 4:1 curren
Thanks Rick, I presume a true quad loop would bring different results with a common feed. I have heard of a single feedline working well with a 5 band quad so I presume that a triangular "Delta Loop"

H I, Herb Well, I expect that your 80/160 delta loop can be made to play well. Do you use EZNEC? It's heck of a lot easier to deal with the interactions with a keyboard and mouse than raising and low
Just try loading the 160 loop. With the other loops inside floating with not feed line to them and leave one end open. Tuning each one may get real touchy. I did this with and 80M folded dipole and w
