Dual band antenna in fender mount

[fremont]

I'm looking at the Tram 1181 (140-170; 430-470) in a NMO fender mount for a dual band application.  My assumption is less than optimal (vs. roof mount, etc.) but do you think it'll play within acceptable SWR range?

Members have had ok results with fender mounts (Comet RS720) on jeeps. Make sure you get a water proof NMO mount/cable that has the sealed bottom, or corrosion will ruin your antenna mount within a year. I would suggest spending just a few more bucks for a Larsen NMO150/450/758 antenna, its great on 2M, 70CM and is wide band enough for GMRS. Below are my results of this antenna with a magmount on the roof of my car:

Also, look at the thread here, it looks like a knock off of the Larsen Antenna that Lscott reviewed here: https://forums.mygmrs.com/topic/1924-larsen-pulse-270-sh/?do=findComment&comment=17016

Saw the Lscott writeup already; lots of good data.  Thanks for the hand.

I assume you mean a mount between the hood and the fender. I use a 1/4 wave antenna with NMO mount for my 2M amateur radio. SWR is 1:1.2 in the middle of the band. Great reception and I can hit repeaters 25+ miles away on low power. Fender mounts are great, unless you’re in a Jeep for some reason. Remember, police cars and ambulances have used them for decades. You should be good.

I reviewed it, either case the Larsen NMO 2/70b is a genuine from Gigaparts. It was bent up in transit and still has a kink in it. Beats me why Gigaparts took a 3 foot long whip and jammed it inside a 6"x6" box.

 

Keep in mind the numbers are from the antenna not being tuned. I simply mounted the whip to the coil/base and took measurements.  I also noted that there was a paint drip on the coil, not sure if that is affecting the numbers. Probably going to contact Larsen to see if I can get a new whip. The 

 

I will be getting clippers out to tune it bit better in the future. I don't transmit much on the GMRS/FRS frequency so the numbers didn't matter.They were acceptable for me as is. Since the signal reports are great. I have to really concentrate on rebuilding the center console, so I can get the FTM400 and android radio (APRS display) in.

I was referring to the Tram antenna the OB posted. I knew yours was a genuine.

Aww ok.. I been having problems with focusing lately. I guess I must have had some more micro strokes. :/
