2005年5月17日 · The Diamond RH77CA Antenna is a good performing antenna. I use it on my BC246T or iCOM IC-R20. I find it is most useful for weak EDACS or MOT systems. It does a fantastic job on Civil and MilAir, VHF Hi, and UHF. No complaints. Will have to buy the SMA version for the upcoming BCD396T. 73 Dave AKA The Tripzter :shock:

2014年11月4日 · Just thought I would throw a quick review out there for the Diamond D3000N Discone antenna, The Big brother so to speak of the D130, it is doing a fantastic job at pulling in the new Peel P25 system, Go Transit and the City of Brampton LTR system.....It has improved my CYYZ airport reception...

2012年7月1日 · Diamond uses the RH prefix for BNC connectors and SRH for SMA. The packaging had a "SMA Connector" sticker on it made from paper. To date, I have not seen a paper sticker used in advertising on a genuine Diamond Antenna. The printing on the antenna itself is going in the wrong direction. Later fakes have the printing going in the correct direction.

2015年12月9日 · I am considering the Diamond Antenna D-130J which has a receive coverage range of 25 MHz to 1300 MHz that matches the Uniden BCD536HP frequency span. Two questions: 1. Does anybody have experience with this antenna? Pros/Cons/Comments? There was a WTB post about this antenna at...

2020年10月14日 · 1. The Yaesu 70DR has an SMA connector on the radio. The Diamond SMA antenna model is SRH77CA. 2. The Diamond RH77CA uses a BNC connector. This antenna would also work on the Yaesu 70DR, but you would need an SMA to BNC adapter. I have both the RH77CA and the SRH77CA antennas. They both work to transmit and receive on handheld amateur radios.

2024年12月11日 · I've had a Diamond X50N for a little over 10 years. It's a great antenna, but there are much better options. A good but conservative compromise between antenna length and gain is the Comet GP6. They are much shorter than the beastly GP9 but still perform fabulous.

2018年7月11日 · It is about marketing, a dBi antenna always specs 2.15 dB greater than same antenna measured in dBd. So buyers are attracted to buying a 6.15 dBi antenna vs a 4 dBd antenna. There are 0 dBd reference dipole antenna designs which are published by NIST. testing against one of these references can yield a dBd value.
