If you would like to get a feel of how my OCF40Q works with a radio, watch the video shown on the left. I don't use a tuner and don't need a tuner. I found the OCF40Q to be a great antenna to use when setting up portable. I never use a tuner and work numerous bands. One antenna, one coax, no tuner, no antenna switch and work numerous bands. What more could you ask for?
When operating portable with the FT-897D, I always cut back on the power output to only 50 watts. This saves on current drain on the battery and is only 3 DB down from 100 watts. That means that the receive end of my signal is only 1/2 of an S unit down from when I would transmit at 100 watts. So instead of the receiver seeing an S 9 with my 100 watts, it would see an S 8-1/2 with my 50 watts out of the radio.
This picture shows the OCF40Q made by, "Hy Power Antenna Company" , erected at the local park I enjoy operating from. The average height of the antenna is 35 feet. One end is tied to a tree and you can see the other end tied to the back stop of the baseball field. Most of my portable antennas are fed with RG 8X. For very short cable runs, 25 feet or less, I've been using RG-174.
Shown in this You Tube video is the MFJ 9020 being used with the LD2012Q. There are times when there are not any trees or high tie points to erect and antenna. You have to be creative. The one end of antenna is tied to the pavilion and the other end is tied to a stick in the ground. The antenna does not have to be flat of high for it to function properly.
