I had bought an antenna model: MFJ-1868 Discone
Xttp://www.mfjenterprises.com/products.php?prodid=MFJ-1868
I understand the frequency Wideband: 25-1300 MHz
What I want to do is "Trim" the antenna to have a start (low frequency) point
of 120Mhz instead of 25Mhz
How much do I need to "Trim"
from 25Mhz to 119Mhz is not needed.
could you guide me thru what needs to be cut?
I mainly need to monitor Air-band - Emergency services on 140-160 400-470 and 800Mhz
btw Is this a good antenna for a scanner?
(seems a little weak in the 800-900mhz)
Thank you.
