Default Is Dominator/Predetor(~6dB gain) competent to CP antennas for LPFM?

If the antenna is for a LPFM station licensed by the FCC (U.S.A.), then
tight restrictions exist on the height of the antenna. Where are you
located?

In any case, as Richard has said, one may buy an antenna for the purpose for
less money.

Hi Bhuvan,


Doubt no longer. You can buy the 6dBi for much less from any number
of other vendors. BEWARE of vendors that give their antennas "names."
Product numbers are sufficient for a commodity market. Better yet,
build your own. All antennas can be scaled to ANY frequency.


The single best advice that you could accept is to raise the antenna
as high as you can.

Thanks for your advice to raise the antenna as high as possible. I can
rise a 40 ft of 1 1/2 inch GI pipe on the rooftop of a four story
building to achieve 90ft hight for the antenna that shouldn't cost me
morethan $300 for the transmission of 100 watt at the transmitter
power. I am looking for the high gain antenna as ERP is not mesured
rather transmitter power is the concern here for FM transmission.


Regards,
Bhuvan

I know the LPFM policy of FCC, that stick to ERP. But I am located in
Nepal. Upon inquary to the communication ministry, the engineer there
stated that they would be concerned with PEP. I can feel the
concerened engineer is either having little or excessive knowledge of
FM transmission. What I have seen here is that they would measure the
transmission of a station as 100 Watt at the transmitter power in my
case. So, often stations are built with a stacked array of broadband
antennas. But I can't afford that antenna system though trying to have
a cost effective antenna system to boost the ERP of my station
operating at 100 Watt @ transmitter power.


Regards,
Bhuvan

The Dominator does have a guarantee to outperform any single other omni directional FM antenna or they will refund your money.

It's one month after delivery for the unconditional money back guarantee. Plenty of time to install the Dominator antenna and compare it against anything else risk free. Then it has a two year warrantee against any defects in materials or workmanship. Again, plenty of time to insure it has been built to handle anything harsh winters or hurricane seasons could throw at it.

Soon there will be another antenna on the market which is made in the usa with quality materials and a hairpin type match. With more gain then any other omni on the market.Higher power handling capability lower input swr and for less money then the competition.And has a wind survival rating over over 100 mph. Feed point swr stay the same no mater what height it is mounted at.Pictures should be on the site within a few months.The antenna is going through its final testing and has already been compared to the dominator antenna with real test equitment and by qualified technicians not in a back yard with a stereo tuner like some only comparing the receive gain.Please feel free to drop me a pm if you have any questions.
