miért nem tudom a 28 MHz-es részt beállítani? mindig csak 32-34 MHz -et mutat, hiába próbálom állítani, mintha nem is akarna ott működni. a = MHz sem beállítható igazán, mintha rosszul raktam volna össze, pedig követtem az előírtakat!

Cushcraft HV4E Vertical Antenna Introduction The HV-4E Vertical Antenna is an economical 18 ft low profile antenna designed to improve operating efficiency and bandwidth on 40M. On 40M the antenna is a center loaded vertical and on 20-10M it is a top loaded vertical.
INSTALLATION The HV-4E was designed as an efficient low profile antenna. The antenna installation MUST be protected with non-metallic fencing to provide personal safety and to prevent antenna damage. The antenna can be installed using the supplied mounting bracket and a suitable ground radial system.
Cushcraft HV4E Vertical Antenna TOOLS AND TIME REQUIRED FOR ASSEMBLY The estimated assembly time for this antenna is 1 hour. Antenna assembly requires the following hand tools: [ ] 5/16" nut driver [ ] 7/16" open end wrench [ ] large wire cutters (to cut aluminum spokes)
Cushcraft HV4E Vertical Antenna ASSEMBLY Lower Mast Assembly Using the two mast section A and the mast section B and two 1.25” hose clamps push the section B into one of the section A about 3 inches and tighten down the hose clamp. Slide the other section A onto the other end of the section B and tighten down the hose clamp.
Cushcraft HV4E Vertical Antenna Slip section D non-slotted end into section C slotted end about 2 inches and clamp with the 0.875” hose clamp (21). Slip section E into section D slotted end about 2 inches and clamp with the 0.875” hose clamp (21).
Cushcraft HV4E Vertical Antenna Base Assembly Assemble the base using the Base Plate (10), four U-Bolts (12), eight ¼” flat washers (13), eight ¼” lock washers (14), and eight ¼-20 nuts. Loosely attach the U-Bolts then slide the fiberglass base insulator (11) into the U-Bolts as shown in the picture and tighten up the U-Bolts holding the fiberglass base insulator.
Cushcraft HV4E Vertical Antenna Radial Spoke Assembly Each radial spoke level requires eight 6-32x.375 SS screws (5) and eight 6-32 KEP nuts (6) for a total of 24 of each. For initial assembly the R1 and R2 radial spokes are 14 inches long and the R3 radial spokes are 18 inches long.
Cushcraft HV4E Vertical Antenna Base Mounting The base mount is designed to clamp to a pipe of 1” to 1-1/2” OD. A galvanized water pipe 1” nominal (OD of 1.335”) is ideal for mounting the antenna base. The exact way of mounting the pipe is up to you but it is suggested that a 4 ft piece of 1”...
Cushcraft HV4E Vertical Antenna ANTENNA TUNING Tuning of the antenna requires some patience with the trimming of the radial spokes for each band. Checking the results can be done with an SWR meter but it is strongly suggested to use an antenna analyzer because the initial tuning will be outside of the amateur bands and using an analyzer will make tracking changes much easier.
Cushcraft HV4E Vertical Antenna CAUTION: Always start tuning on 40 meters and adjust each band progressively higher in frequency. Adjustment of a lower frequency band will always have the most effect on the next higher frequency band. The tendency of the interaction is that if you move one band higher ALL the other bands move higher, but only very slightly.
Cushcraft HV4E Vertical Antenna SAFETY GROUNDING CONSIDERATIONS SAFETY GROUNDING MUST be provided to protect equipment, property, and persons from the hazards of lighting strikes and other weather related electrical discharges. In addition the coaxial cable feeding the antenna should have the shield grounded to eliminate the risk of any indoor equipment failure that would allow hazardous voltages to appear indoors creating a shock hazard.
