I managed to get OK reception (in a fairly marginal area) using one of the "One-For-All" models. It was the amplified model with the square-ish loop UHF and pull-up VHF aerials, and 39db of gain - from memory it was about $80. I had previously tried a couple of cheaper ones, and another One-for-All model that looked like a black rectangle about an inch wide and a foot tall and had the option of powering off USB, and their performance wasn't nearly as good (*).

If reception is marginal, an indoor aerial will *never* perform as well as a rooftop one. If your reception is marginal it may never work, regardless of model. My main TV has a rooftop aerial with a masthead amplifier and works much better - it was just infeasible to cable it to the bedroom.

* performance on anything indoors, and even my rooftop aerial, was pretty awful when Kaukau had muxes in the 700Mhz band, after the channel re-stacking it's much better.

The rectangular shaped One for All model sounds like the one I bought a few months ago to use temporarily when I was having having trouble with my satellite dish. It worked perfectly for me on the Mediaworks Mux, and was okay on the Kordia Mux with careful placement. It's designed to stand upright but because I was pointing it at Kaukau (Wellington) which is horizontally polarised I laid it on its side which appeared to work slightly better although I can't be sure.

My house very nearly has line of sight to Kaukau - there is just the crest of another hill in the way. With any significant obstructions I would imagine that any indoor antenna would probably be useless.

Strange design - most transmitters are horizontal polarisation, so you would expect the aerial to be set-up for horizontal polarisation when standing upright.
