|Chimney Mount||KK6OZV||on 5/1/15|
|If your chimney is made of brick and has internal ceramic flue pipes, then you could use such a mount without fear of melting coax. However,, the chimney must be in excellent physical condition before mounting an antenna in it. Antennas tend to be rough on chimneys during wind storms, so the condition of the chimney must be monitored frequently. Also, check with your local zoning laws to see if such an installation is allowed. I have heard that due to safety considerations (falling brick), chimney mounts are no longer allowed in new installations.|
|MFJ-949E Tuner with Comet SBB-5||AF9U||on 7/11/14|
Check the specification of the MFJ-949E. You will see the tuner is designed to operate between 1.8 and 30 MHz. It will not work on 2 meters.
A good rule of thumb is to use a resonant antenna, when possible, so no antenna tuner is needed. There is no need to add a tuner if your mag mount antenna works well without one.
I used to use the same type of antenna when I lived in an apartment back in the 80's. I had a Larsen mag mount on top of a well seasoned baking pan. The outfit was placed on a flat roof, about 10 feet away from my shack window. It worked great.

|Antenna Polarization for FM contesting||Gringo6||on 4/11/14|
|If FM is all you have, FM polarization is fine.
I appreciate FM operators during VHF QSO parties. FM contacts added to my overall score, each time I have participated. During lulls in the event, I always check out the 2 meter FM simplex frequencies (excluding 146.520 MHz). Those 20 or so extra QSOs can add to a serious contester's score.
It would be nice to see some new participants during contests. Maybe we should have an FM only catagory?
