 | The AA-75 Antenna Accessory kit contains the end insulators and a specially constructed strain relief center insulator needed for constructing dipole type antennas. |
| The center insulator is designed to provide strain relief for RG58 coax feedline for dipole antennas, which must be cut to length for the desired operating frequency. ( See the ARRL Handbook for proper length ). |
| This insulator also accepts and provides strain relief for 300 to 500 ohm twin lead feed line for multi-band antennas using a balun and a matching unit. |
| The Drake MN-7 or MN-2700 Matching Networks with a B-1000 Balun will match a 135' center fed horizontal antenna fed with 60 to 70 feet of balanced line over the 160-10 meter amateur bands. |
