Hi guys:

I'm a long-time lurker here and by no means an antenna expert. With the transition to ATSC and especially the FCC's desire in the US to further reduce the UHF spectrum available to broadcasters, the noise issues pertaining to VHF-Lo have been clearly articulated here and on other related websites.

I have also had a long-time interest in shortwave and mediumwave broadcasting. I recently came across some literature where H-wave antennas are being promoted as a solution over those frequencies to improve reception that would be otherwise complicated by local noise:

I also found a reference where H-wave antennas are mentioned as being potentially useful for VHF-Lo (Band I) reception:

You will note that the Pixel literature promotes SNR rather than gain, so I presume the gain of these antennas is not particularly high. That said, if the issue with VHF-Lo is more one of SNR than gain, H-wave antennas might be reasonable. If comparatively small H-wave antennas can be made for MW and HF broadcasting, it makes me wonder if an array of Mobius Loop H-wave antennas for VHF-Lo might be a reasonable size, thereby providing modest gain at high SNR.

What do you Think?

H-Field Practicality

Holl_ands:

Thanks for your thoughts and the links. It's clear that an H-Field antenna is not a cure-all for the problems on VHF-Lo.
