GENERAL. ATU(Antenna Tuning Unit), is Impedance Matching device installed at Outside(near the Antenna) so that transmitter output can radiates better through the antenna. This ATU can be manual or automatically tuned. When the ATU is at Automatic-mode, Auto Tune Motor with Circuit module drives Variable Inductor to make the best Impedance matching status. In addition, a doublet must always be used with an antenna tuning unit (ATU) due to the impedance mismatches. 80m doublets appear to be the largest commonly used.

  • Bristol is ranked top, thanks to its long-term property growth (annual average of 5.1 per cent), as well as the lowest number of long-term property vacancies (0.6 per cent), and over a quarter of residents (27 per cent) renting privately
  • ranked second and third respectively, Oxford and Cambridge are once again seen as profitable investment locations after coming fourth and second in 2021
  • Luton shot up seven places to enter the top 10 for the first time. This is largely thanks to average annual price growth of 5.2 per cent offering landlords an attractive long-term return on investment
  • London has dropped to sixth, but remains in the top 10 due to its long-term stability and high demand from tenants
