[amsat-bb] Commercial omni satellite antennas?

Hello all,

Does anyone know of commercial sources of any of the following omnidirectional satellite antennas suitable for amateur use?

- QHA - Turnstile - Lindenblad

There are many plans for constructing such antennas, but I haven’t found any commercial varieties through common Amateur sources (other than M2 which makes egg beaters).

Thanks & 73! Ken VA7KBM
