I have made a 4 element deltaloop on a 30 foot boom for 20/17/15/12/10

re-installing at my new address. The gain for 4 elements is around 11.5
dbd. If anyone is interested, I have put together a website that

11.5 dBd on what band?  Is that the free space gain, or if not, what is
the free space gain? If the loops are really doing something vs dipoles, it should beat a 4 element SteppIR on a 32 foot boom.
They claim 11.6 to 12.7 dBd gain, I guess in free space (no height
is listed).  See:  http://www.steppir.com/4-element-yagi.
