Antennas for portable equipment presented below:
The first antenna presented is from Jetfon a 2m / 70 cm dual-band handheld radio antenna led stubby Tx, the price is 15 EUR, technical specifications here:
|DB-110 M/F||1/4 λ||<= 11.5 cm.||<= 11 gr.||10 W||SMA M / F||Red (M) / Green (F)|
The next antenna I have tested and used on a daily basis is from D-ORIGINAL, dual-band 70 CM and 2 m lambda, price expected 10 EUR, specs below:
|DX-DB-45-LED-M/F||1/6 λ?||40 mm.||< 10 gr.||10 W||SMA M / F||Black with red LED light|
One of the antennas which are my daily driver in terms of performance is Nagoya NA-701, dual-band 70 CM and 2 m lambda, price expected 20 EUR, technical specs below:
|NA-701||1/4 λ||17 cm.||< 25 gr.||10 W||SMA M, F or BNC||50 Ω|
Besides a good performance in the field for transmission (acceptable SWR) offers wide receiving coverage 120 / 150 / 300 / 450 / 900 MHz.
One of the radials I am using is from Komunica which is performing well, a couple of tech details:
|PWR-SRH-519||3 dBi||1/4 λ||50 Ω||10 W||SMA|
A mini dual-band antenna (144/430 Mhz) with extended receive coverage (150/300/450/800Mhz) weighs just 9 grams and 21 cm length.
