The pvc might come in handy to make a balun. If using PVC ask for the Ultra Violet (UVA) resistant type as it will last longer outdoors. Your idea of using a vertical for an ARES (or RACES) antenna is bad. You would be much better off with a dipole or doublet at least 22 feet high, but preferably around 30-35 feet high.ALPS Variable Capacitor meshed adjustable around 450 pf for Crystal Radio Amplifier Homebrew diy kit qrp Loop Antenna Tuner am fm mw sw Shortwave Radio.

Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.

Calculator for Short Wave (SW) Radio Coil. This calculator will find the inductance value of the short wave (SW) radio coil required for building a ferrite rod antenna given the value of the variable capacitor. The default values are for the coverage of the SW frequency range of 1700 kHz to 30000 kHz, utilising a 224 pF variable capacitor.Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered.
