Can the DMV Pro be made smaller and still cover the 80m band?
• Yes it can, but in the development stages we chose not to accept the loss of efficiency and performance. The DMV Pro was designed to work effectively from the lowest band first. If we could have made the physical size smaller without a serious loss of performance, then of course we would have done it. The feed back from our customers is we have got the balance between size and performance just right. 2) I’m thinking of buying a well known portable dipole; it is multiband and no ATU is required. Should I go ahead? The market offers several short portable diploes, they require precise adjustment when setting up to obtain resonance, 80m & 40m bandwidth is typically less than 30kHz. The promotional key words to watch out for are, “no ATU is required”. Each time you want to change frequency or move bands, the dipole will have to be lowered and the inductance altered either by moving taps, changing loading coils and adjustment of telescopic end sections. This procedure has to be carried ou
