Anyone know if the variable cap, that I'm assuming is included
in this kit, will suffice for the bc band loop I want to build ?

BRIAN,

Since this is an AM & FM Radio 'Kit' it most likely uses a
"Miniature Poly-film Variable Tuning Capacitor" for AM & FM Bands
CAPS= http://www.oselectronics.com/ose_p98.htm
Part Number: BC-88

Ideal Variable Tuning Capacitor for miniature circuitry and use
as exact-duplicate replacement in current transistor receivers.
Tunes AM Band from 540Khz to 1600Khz and FM band from 88Mhz to
108Mhz. Rotates through a full 180°

Maximum Capacity:
AM/MW Antenna Section AM 21-152PF, Oscillator Section AM, 10-74PF.
FM Antenna Section FM 23-44PF, Oscillator Section FM, 14-23PF

Trimmer Capacity: variable to over 12PF.
Trimmer adjustment on rear of case.

Completely enclosed to clear polyethylene
plastic case to protect plates.
Includes calibrated dial, screw, and knob.
Small size, 3/4" Square x 1/2" Deep.


BETTER ALTERNATIVE:
AM/MW "Only" Tuning Capacitor: (Good for AM/MW Loop Antennas)
For your Loop Antenna 'Project' you may wish to consider a Capacitor
that is specifically designed to work within the Band Range of the
AM/MW Broadcast band.

"Miniature 1 Gang Poly-Film Variable Tuning Capacitor For Broadcast Band"
CAPS= http://www.oselectronics.com/ose_p98.htm
Part Number: BC-280

Tunes AM band from 540 kHz to 1600 kHz. Ideal Variable Tuning
Capacitor for miniature circuitry and use as exact-duplicate
replacement in current transistor receivers.
Works great in crystal radio sets. (Loop Antennas)
- Rotates through a full 180°
- Maximum Capacity: Single section tunes from 10-280pf.
- Completely enclosed in a clear polyethylene
plastic case to protect plates.
- Includes Calibrated Dial, Screw, and Knob.
Small size, 3/4" Square x 1/2" Deep.

REQUIRES: Loop Antenna Inductance of about 350 uH
when using a Variable Capacitor Range of 10 to 280 pf.
