USER-MANUAL_M-104

  • Is the antenna waterproof, is it usable it rains?

Yes it is usable in rain – The antenna parameter would change if it’s wet though – It applies not only but also for all antennas when they are getting wet.

  • Why my resonant frequency is higher and how can i tune it down?

You should revisit your counterpoise set up. A good counterpoise is important for M-104. If you are using radials as counterpoise, You can use them with supplied ring terminals – At least 1 radial is needed above 14MHz, and more than 3 radials is recommended on 7MHz.

  • I use a multimeter to test and figured the center conductor and the shield are shorted – Is my antenna defective?

Rest assured – It’s our unique design in the base and yes it will indicate as shorted if you use a multimeter to test the center and the shield. No worries it is not a defective unit.
