If you’re on a wideband transmitter and really do need a high gain aerial (and most people don’t) we still recommend a high gain wideband over a T group despite the fact widebands are technically obsolete. This is because all T groups start dropping off in their gain curves in the mid high (channel) 50s to try and minimise 4G interference, though I’m sceptical if they’re much good at it….. But if you’re in a poor spot you need high gain in the high 50s ! So I’d go for a high gain wideband and if you do have 4G problems I’d get a filter, the latter will work better at preventing 4G interference anyway. This is a particularly good strategy whilst good quality filters are still available free from at800 ! !
If on a K group transmitter, and in a poor spot, we recommend our K group aerials.
The DY14 Wideband is a “Double Yagi” type aerial and is well made, in fact these antennas have better build quality than most of the more common X Beam type aerials. The DY14WB has a “balun”, a cradle and a tilting clamp for poles up to 2in.
Size for size the DY14WB is the best high gain wideband I’ve ever come across, in fact its performance is even reasonable in the A and B groups, though obviously a decent group A aerial (or our XB16 group B) will have more gain in the relevant groups frequencies.
The DY14 is a good choice for someone needing to fit a high gain wideband aerial in the loft because it’s only 5 ft long, which is pretty compact for an aerial with this amount of gain.
Due to wind loading considerations if fitting to a 10ft pole we advise using the 2” variety.
